+
+  target_sources(<target>
+    [<INTERFACE|PUBLIC|PRIVATE>
+     [FILE_SET <set> [TYPE <type>] [BASE_DIRS <dirs>...] [FILES <files>...]]...
+    ]...)
+
+Adds a file set to a target, or adds files to an existing file set. Targets
+have zero or more named file sets. Each file set has a name, a type, a scope of
+``INTERFACE``, ``PUBLIC``, or ``PRIVATE``, one or more base directories, and
+files within those directories. The only acceptable type is ``HEADERS``. The
+optional default file sets are named after their type. The target may not be a
+custom target or :prop_tgt:`FRAMEWORK` target.
+
+Files in a ``PRIVATE`` or ``PUBLIC`` file set are marked as source files for
+the purposes of IDE integration. Additionally, files in ``HEADERS`` file sets
+have their :prop_sf:`HEADER_FILE_ONLY` property set to ``TRUE``. Files in an
+``INTERFACE`` or ``PUBLIC`` file set can be installed with the
+:command:`install(TARGETS)` command, and exported with the
+:command:`install(EXPORT)` and :command:`export` commands.
+
+Each ``target_sources(FILE_SET)`` entry starts with ``INTERFACE``, ``PUBLIC``, or
+``PRIVATE`` and accepts the following arguments:
+
+``FILE_SET <set>``
+
+  The name of the file set to create or add to. It must contain only letters,
+  numbers and underscores. Names starting with a capital letter are reserved
+  for built-in file sets predefined by CMake. The only predefined set name is
+  ``HEADERS``. All other set names must not start with a capital letter or
+  underscore.
+
+``TYPE <type>``
+
+  Every file set is associated with a particular type of file. ``HEADERS``
+  is currently the only defined type and it is an error to specify anything
+  else. As a special case, if the name of the file set is ``HEADERS``, the
+  type does not need to be specified and the ``TYPE <type>`` arguments can be
+  omitted. For all other file set names, ``TYPE`` is required.
+
+``BASE_DIRS <dirs>...``
+
+  An optional list of base directories of the file set. Any relative path
+  is treated as relative to the current source directory
+  (i.e. :variable:`CMAKE_CURRENT_SOURCE_DIR`). If no ``BASE_DIRS`` are
+  specified when the file set is first created, the value of
+  :variable:`CMAKE_CURRENT_SOURCE_DIR` is added. This argument supports
+  :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+  No two base directories for a file set may be sub-directories of each other.
+  This requirement must be met across all base directories added to a file set,
+  not just those within a single call to ``target_sources()``.
+
+``FILES <files>...``
+
+  An optional list of files to add to the file set. Each file must be in
+  one of the base directories, or a subdirectory of one of the base
+  directories. This argument supports
+  :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+  If relative paths are specified, they are considered relative to
+  :variable:`CMAKE_CURRENT_SOURCE_DIR` at the time ``target_sources()`` is
+  called. An exception to this is a path starting with ``$<``. Such paths
+  are treated as relative to the target's source directory after evaluation
+  of generator expressions.
+
+The following target properties are set by ``target_sources(FILE_SET)``,
+but they should not generally be manipulated directly:
+
+* :prop_tgt:`HEADER_SETS`
+* :prop_tgt:`INTERFACE_HEADER_SETS`
+* :prop_tgt:`HEADER_SET`
+* :prop_tgt:`HEADER_SET_<NAME>`
+* :prop_tgt:`HEADER_DIRS`
+* :prop_tgt:`HEADER_DIRS_<NAME>`
+
+Target properties related to include directories are also modified by
+``target_sources(FILE_SET)`` as follows:
+
+:prop_tgt:`INCLUDE_DIRECTORIES`
+
+  If the ``TYPE`` is ``HEADERS``, and the scope of the file set is ``PRIVATE``
+  or ``PUBLIC``, all of the ``BASE_DIRS`` of the file set are wrapped in
+  :genex:`$<BUILD_INTERFACE>` and appended to this property.
+
+:prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES`

+  ``INTERFACE`` or ``PUBLIC``, all of the ``BASE_DIRS`` of the file set are
+  wrapped in :genex:`$<BUILD_INTERFACE>` and appended to this property.

+Distribution XML Template
+^^^^^^^^^^^^^^^^^^^^^^^^^

+CPack uses a template file to generate the ``distribution.dist`` file used

+:variable:`CMAKE_MODULE_PATH` variable. CPack will then pick up the project's

+

+Module Functions and Macros
+---------------------------
+
+Modules may provide CMake functions and macros defined by the `function()`_
+and `macro()`_ commands.  To avoid conflicts across modules, name the
+functions and macros using the prefix ``<ModuleName>_`` followed by the
+rest of the name, where ``<ModuleName>`` is the exact-case spelling of
+the module name.  We have no convention for the portion of names after
+the ``<ModuleName>_`` prefix.
+
+For historical reasons, some modules that come with CMake do not follow
+this prefix convention.  When adding new functions to these modules,
+discussion during review can decide whether to follow their existing
+convention or to use the module name prefix.
+
+Documentation of public functions and macros should be provided in
+the module, typically in the main `module documentation`_ at the top.
+For example, a ``MyModule`` module may document a function like this::
+
+  #[=======================================================================[.rst:
+  MyModule
+  --------
+
+  This is my module.  It provides some functions.
+
+  .. command:: MyModule_Some_Function
+
+    This is some function:
+
+    .. code-block:: cmake
+
+      MyModule_Some_Function(...)
+  #]=======================================================================]
+
+Documentation may alternatively be placed just before each definition.
+For example, a ``MyModule`` module may document another function like this::
+
+  #[=======================================================================[.rst:
+  .. command:: MyModule_Other_Function
+
+    This is another function:
+
+    .. code-block:: cmake
+
+      MyModule_Other_Function(...)
+  #]=======================================================================]
+  function(MyModule_Other_Function ...)

+
+In general, lists do not support elements containing ``;`` characters.
+To avoid problems, consider the following advice:
+
+* The interfaces of many CMake commands, variables, and properties accept
+  semicolon-separated lists.  Avoid passing lists with elements containing
+  semicolons to these interfaces unless they document either direct support
+  or some way to escape or encode semicolons.
+
+* When constructing a list, substitute an otherwise-unused placeholder
+  for ``;`` in elements when.  Then substitute ``;`` for the placeholder
+  when processing list elements.
+  For example, the following code uses ``|`` in place of ``;`` characters:
+
+  .. code-block:: cmake
+
+    set(mylist a "b|c")
+    foreach(entry IN LISTS mylist)
+      string(REPLACE "|" ";" entry "${entry}")
+      # use "${entry}" normally
+    endforeach()
+
+  The :module:`ExternalProject` module's ``LIST_SEPARATOR`` option is an
+  example of an interface built using this approach.
+
+* In lists of :manual:`generator expressions <cmake-generator-expressions(7)>`,
+  use the :genex:`$<SEMICOLON>` generator expression.
+
+* In command calls, use `Quoted Argument`_ syntax whenever possible.
+  The called command will receive the content of the argument with
+  semicolons preserved.  An `Unquoted Argument`_ will be split on
+  semicolons.
+
+* In :command:`function` implementations, avoid ``ARGV`` and ``ARGN``,
+  which do not distinguish semicolons in values from those separating values.
+  Instead, prefer using named positional arguments and the ``ARGC`` and
+  ``ARGV#`` variables.
+  When using :command:`cmake_parse_arguments` to parse arguments, prefer
+  its ``PARSE_ARGV`` signature, which uses the ``ARGV#`` variables.
+
+  Note that this approach does not apply to :command:`macro` implementations
+  because they reference arguments using placeholders, not real variables.

+
+Compiler id for MCST LCC compilers is now ``LCC``, not ``GNU``.
+
+CMake 3.23 and above recognize MCST LCC compiler as a different from ``GNU``,
+with its own command line and set of capabilities.
+CMake now prefers to present this to projects by setting the
+:variable:`CMAKE_<LANG>_COMPILER_ID` variable to ``LCC`` instead
+of ``GNU``. However, existing projects may assume the compiler id for
+LCC is ``GNU`` as it was in CMake versions prior to 3.23.
+Therefore this policy determines for MCST LCC compiler which
+compiler id to report in the :variable:`CMAKE_<LANG>_COMPILER_ID`
+variable after language ``<LANG>`` is enabled by the :command:`project`
+or :command:`enable_language` command.  The policy must be set prior
+to the invocation of either command.
+
+The ``OLD`` behavior for this policy is to use compiler id ``GNU`` (and set
+:variable:`CMAKE_<LANG>_COMPILER_VERSION` to the supported GNU compiler version.)
+``NEW`` behavior for this policy is to use compiler id ``LCC``, and set
+:variable:`CMAKE_<LANG>_SIMULATE_ID` to ``GNU``, and
+:variable:`CMAKE_<LANG>_SIMULATE_VERSION` to the supported GNU compiler version.
+
+This policy was introduced in CMake version 3.23.  Use the
+:command:`cmake_policy` command to set this policy to ``OLD`` or ``NEW`` explicitly.
+Unlike most policies, CMake version |release| does *not* warn
+by default when this policy is not set and simply uses ``OLD`` behavior.
+See documentation of the
+:variable:`CMAKE_POLICY_WARNING_CMP0129 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
+variable to control the warning.

+CMake 3.23 Release Notes
+************************
+
+.. only:: html
+
+  .. contents::
+
+Changes made since CMake 3.22 include the following.
+
+New Features
+============
+
+Presets
+-------
+
+* :manual:`cmake-presets(7)` files now support schema version ``4``.
+
+* :manual:`cmake-presets(7)` files now have an optional ``include`` field,
+  which allows the files to include other files.
+
+* :manual:`cmake-presets(7)` files now support a ``${fileDir}`` macro, which
+  contains the directory containing the preset file.
+
+* :manual:`cmake-presets(7)` gained support for specifying the
+  ``resolvePackageReferences`` command line option in a build preset to control
+  restoration behavior of package references from external package managers.
+  Currently this is only supported by the Visual Studio generator to support
+  restoring packages from NuGet. Other generators ignore this option.
+
+Generators
+----------
+
+* The :ref:`Visual Studio Generators` for VS 2019 and above learned to
+  support .NET SDK-style project files (``.csproj``) for C# projects.
+  See the :prop_tgt:`DOTNET_SDK` target property and corresponding
+  :variable:`CMAKE_DOTNET_SDK` variable.  :command:`add_custom_command`
+  is not yet supported in .NET SDK-style projects.
+
+* The :ref:`Visual Studio Generators` for VS 2017 and above learned to
+  use portable instances of Visual Studio not known to the VS installer.
+  See the :variable:`CMAKE_GENERATOR_INSTANCE` variable.
+
+Command-Line
+------------
+
+* The :manual:`cmake(1)` ``--build`` command, when used with
+  :ref:`Visual Studio Generators` on projects that set the
+  :prop_tgt:`VS_PACKAGE_REFERENCES` target property, now automatically
+  restores package references from NuGet.  The cache variable
+  :variable:`CMAKE_VS_NUGET_PACKAGE_RESTORE` may be set to toggle this behavior
+  in a build tree.  Use the ``--resolve-package-references=<on|off|only>``
+  command-line option to control the behavior on one invocation.
+
+* The :manual:`cmake(1)` command line tool gained a ``--debug-find-pkg=``
+  option to enable debug messages under specific :command:`find_package`
+  calls.
+
+* The :manual:`cmake(1)` command line tool gained a ``--debug-find-var=``
+  option to enable debug messages for ``find_*`` calls that use specific
+  result variables.
+
+Compilers
+---------
+
+* The IBM Open XL C/C++ compiler, based on LLVM, is now supported with
+  compiler id ``IBMClang``.
+
+* The MCST LCC compiler is now supported with compiler id ``LCC``.
+  See policy :policy:`CMP0129`.
+
+File-Based API
+--------------
+
+* The :manual:`cmake-file-api(7)` "codemodel" version 2 ``version`` field
+  has been updated to ``2.4``.
+
+* The :manual:`cmake-file-api(7)` "codemodel" version 2 ``directory``
+  object ``installers`` field gained a new ``fileSet`` installer type.
+
+Commands
+--------
+
+* The :command:`define_property` command gained a new
+  ``INITIALIZE_FROM_VARIABLE`` option to cause a target property to be
+  initialized from a variable when a target is created.
+
+* The :command:`install(TARGETS)` command gained a new ``FILE_SET`` argument,
+  which can be used to install header file sets associated with a target.
+
+* The :command:`string(TIMESTAMP)` and :command:`file(TIMESTAMP)` commands now
+  support the ``%f`` specifier for microseconds.
+
+* The :command:`target_sources` command gained a new ``FILE_SET`` mode, which
+  can be used to add headers as header-only source files of a target.
+
+Variables
+---------
+
+* The :variable:`CMAKE_CUDA_ARCHITECTURES` variable and associated
+  :prop_tgt:`CUDA_ARCHITECTURES` target property now support the
+  ``all``, and ``all-major`` values for CUDA toolkit 7.0+.
+
+* The :variable:`CMAKE_IGNORE_PREFIX_PATH` and
+  :variable:`CMAKE_SYSTEM_IGNORE_PREFIX_PATH` variables were added
+  to tell the :command:`find_package`, :command:`find_program`,
+  :command:`find_library`, :command:`find_path`, and :command:`find_file`
+  commands to ignore specified prefixes.
+
+* The :variable:`CMAKE_LINK_LIBRARIES_ONLY_TARGETS` variable and
+  corresponding :prop_tgt:`LINK_LIBRARIES_ONLY_TARGETS` target
+  property were added to optionally require that all link items
+  that can be target names are actually names of existing targets.
+
+Properties
+----------
+
+* The :prop_tgt:`HEADER_SETS` and :prop_tgt:`INTERFACE_HEADER_SETS` read-only
+  target properties were added to list header sets associated with a target.
+
+* The :prop_tgt:`HEADER_SET` and :prop_tgt:`HEADER_SET_<NAME>` target
+  properties were added to list files in the default header set
+  and named header sets, respectively.
+
+* The :prop_tgt:`HEADER_DIRS` and :prop_tgt:`HEADER_DIRS_<NAME>` target
+  properties were added to specify the base directories of the default
+  header set and named header sets, respectively.
+
+* The :prop_tgt:`IMPORTED_NO_SYSTEM` target property was added to
+  specify that an :ref:`Imported Target <Imported Targets>` should
+  not be treated as a system library (i.e. its include directories
+  are not automatically ``SYSTEM``).
+
+* The :prop_tgt:`XCODE_EMBED_PLUGINS <XCODE_EMBED_<type>>` target property
+  was added to tell the :generator:`Xcode` generator what targets to put in
+  the ``Embed PlugIns`` build phase.
+
+* The :prop_tgt:`XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE` target property
+  and supporting :variable:`CMAKE_XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE`
+  variable were added to tell the :generator:`Xcode` generator to enable
+  specifying the Xcode scheme option property ``GPU Frame Capture``.
+
+Modules
+-------
+
+* The :module:`CheckPIESupported` module now supports the ``OBJC``,
+  ``OBJCXX``, ``CUDA``, and ``HIP`` languages.  It also now honors
+  :variable:`CMAKE_SYSROOT` and :variable:`CMAKE_OSX_SYSROOT`.
+
+* The :module:`ExternalProject` module's :command:`ExternalProject_Add`
+  command gained support for a ``USES_TERMINAL_PATCH`` option to give
+  the patch step exclusive terminal access.
+
+* The :module:`FindCUDAToolkit` module now provides a target for
+  ``libcufft_static_nocallback``, if found.
+
+* The :module:`FindGLUT` module now provides the ``GLUT_INCLUDE_DIRS``
+  result variable to conform with naming conventions documented in the
+  :manual:`cmake-developer(7)` manual.  This supersedes the legacy
+  ``GLUT_INCLUDE_DIR`` variable.
+
+* The :module:`FindGTest` module now provides a target for GMock, if found.
+
+* The :module:`FindVulkan` module now provides a ``Vulkan_VERSION`` result
+  variable reporting the version number.
+
+CTest
+-----
+
+* :manual:`ctest(1)` gained a new :variable:`CTEST_SUBMIT_INACTIVITY_TIMEOUT`
+  variable, which can be used to specify a timeout for submission inactivity.
+
+CPack
+-----
+
+* The :cpack_gen:`CPack productbuild Generator` gained the new
+  :variable:`CPACK_PRODUCTBUILD_DOMAINS`,
+  :variable:`CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE`,
+  :variable:`CPACK_PRODUCTBUILD_DOMAINS_USER`, and
+  :variable:`CPACK_PRODUCTBUILD_DOMAINS_ROOT` variables for
+  adding the domains element to the Distribution XML. With these variables,
+  it is now possible to install products to the user's home directory
+  without requiring administrative privileges.
+
+* The :cpack_gen:`CPack productbuild Generator` gained a new variable,
+  :variable:`CPACK_PRODUCTBUILD_IDENTIFIER`, used to customize the unique
+  product identifier associated with the product.
+
+* The ``CPack.distribution.dist.in`` template used by the
+  :cpack_gen:`CPack productbuild Generator` and
+  :cpack_gen:`CPack PackageMaker Generator` was updated to use a new
+  ``CPACK_APPLE_PKG_INSTALLER_CONTENT`` variable for its main content.
+  This replaced the previously undocumented and now deprecated
+  ``CPACK_PACKAGEMAKER_CHOICES`` variable.
+
+* The :cpack_gen:`CPack IFW Generator` gained the new
+  :variable:`CPACK_IFW_ARCHIVE_FORMAT` and
+  :variable:`CPACK_IFW_ARCHIVE_COMPRESSION` variables for setting the
+  format used when packaging new component data archives, and choosing
+  the compression level used.
+  These features are available for QtIFW 4.2 and newer.
+
+* The :cpack_gen:`CPack IFW Generator` gained new
+  :variable:`CPACK_IFW_PACKAGE_DISABLE_COMMAND_LINE_INTERFACE` variable to
+  prevent the user from passing any consumer command to the installer, like
+  ``install``, ``update``, and ``remove``.
+  This feature is available for QtIFW 4.0 and newer.
+
+* The :cpack_gen:`CPack IFW Generator` gained the new
+  :variable:`CPACK_IFW_PACKAGE_PRODUCT_IMAGES` variable for adding a
+  list of images to be shown on the ``PerformInstallationPage``.
+  This feature is available for QtIFW 4.0 and newer.
+
+* The :cpack_gen:`CPack IFW Generator` gained the new
+  :variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM`,
+  :variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM_ARGUMENTS`, and
+  :variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM_DESCRIPTION` variables for
+  executing a command after the installer is done if the user accepts
+  the action.  This feature is available for QtIFW 4.0 and newer.
+
+* The :cpack_gen:`CPack IFW Generator` gained the new
+  :variable:`CPACK_IFW_PACKAGE_SIGNING_IDENTITY` variable for specifying a
+  code signing identity to be used for signing the generated app bundle.
+  This feature is available on macOS only, and for QtIFW 3.0 and newer.
+
+* The :cpack_gen:`CPack WIX Generator` gained a new variable,
+  :variable:`CPACK_WIX_SKIP_WIX_UI_EXTENSION`, to skip the inclusion
+  of WixUIExtensions.
+
+Deprecated and Removed Features
+===============================
+
+* :manual:`cmake(1)` now warns when multiple source paths are specified,
+  as in ``cmake -S src1 src2``.  This has never been officially documented
+  or supported, but older versions accidentally accepted multiple source
+  paths and used the last path specified.  Update scripts to avoid
+  passing multiple source path arguments.
+
+* The :manual:`cpack(1)` undocumented ``OSXX11`` generator has been removed.
+
+* The previously undocumented ``CPACK_PACKAGEMAKER_CHOICES`` variable used in
+  the ``CPack.distribution.dist.in`` template has been replaced by a new
+  ``CPACK_APPLE_PKG_INSTALLER_CONTENT`` variable. This only affects projects
+  that were providing their own custom ``CPack.distribution.dist.in`` template
+  file, but still relied on ``CPACK_PACKAGEMAKER_CHOICES`` being set. Those
+  custom template files should be updated to use
+  ``CPACK_APPLE_PKG_INSTALLER_CONTENT`` instead, or to fully define all the
+  template file's contents without relying on substitution of either variable.
+
+Other Changes
+=============
+
+* The :cpack_gen:`CPack DragNDrop Generator` no longer attaches
+  :variable:`CPACK_RESOURCE_FILE_LICENSE` as the license agreement in
+  the generated ``.dmg`` unless explicitly activated by a
+  :variable:`CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` option.
+  In CMake projects, the :module:`CPack` module enables the option
+  by default for compatibility.
+
+* ``CUDA`` targets may now enable both :prop_tgt:`CUDA_SEPARABLE_COMPILATION`
+  and :prop_tgt:`CUDA_PTX_COMPILATION`.
+
+* ``CUDA`` compiler detection now:
+
+  * issues an error in all cases when it's unable to compute the default
+    architecture(s) if required (see :policy:`CMP0104`),
+
+  * handles ``OFF`` for :variable:`CMAKE_CUDA_ARCHITECTURES` on Clang,
+
+  * supports the theoretical case of multiple default architectures, and
+
+  * tries to detect invalid architectures and issue an error.
+
+* ``CUDA`` with Clang now implements policy :policy:`CMP0105` and
+  the ``$<DEVICE_LINK:...>`` and ``$<HOST_LINK:...>``
+  :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+* The :command:`define_property` command's ``BRIEF_DOCS`` and ``FULL_DOCS``
+  arguments are now optional.
+
+* :manual:`ccmake(1)` may now be enabled on Windows when building
+  CMake from source.  This is experimental, and so is not included
+  in official distributions.
+
+Updates
+=======
+
+Changes made since CMake 3.23.0 include the following.
+
+3.23.1
+------
+
+* The :command:`target_sources` ``FILE_SET`` feature added in CMake 3.23.0
+  does not yet place header files properly in Apple :prop_tgt:`FRAMEWORK`
+  targets.  Pending further work in a future version of CMake, it is now
+  an error to add a ``FILE_SET`` of type ``HEADERS`` to such targets on
+  Apple platforms.
+
+* The :prop_tgt:`HEADER_SETS` and :prop_tgt:`INTERFACE_HEADER_SETS` target
+  properties added in CMake 3.23.0 are now read-only records of the header
+  sets created by the :command:`target_sources` command.
+
+3.23.2
+------
+
+* The ``CPACK_PACKAGEMAKER_CHOICES`` variable used in the
+  ``CPack.distribution.dist.in`` template file was replaced by a new
+  ``CPACK_APPLE_PKG_INSTALLER_CONTENT`` variable in CMake 3.23.0.
+  This broke projects that provided their own template file but still
+  expected the ``CPACK_PACKAGEMAKER_CHOICES`` variable to be defined.
+  The old ``CPACK_PACKAGEMAKER_CHOICES`` variable is now also set to the
+  same content as it was before, but it is formally deprecated.

-See native build system documentation for allowed instance values.
+:ref:`Visual Studio Generators` support instance specification for

+may be set as a cache entry selecting an instance of Visual Studio
+via one of the following forms:
+
+* ``location``
+* ``location[,key=value]*``
+* ``key=value[,key=value]*``
+
+The ``location`` specifies the absolute path to the top-level directory
+of the VS installation.
+
+The ``key=value`` pairs form a comma-separated list of options to
+specify details of the instance selection.
+Supported pairs are:
+
+``version=<major>.<minor>.<date>.<build>``
+  .. versionadded:: 3.23
+
+  Specify the 4-component VS Build Version, a.k.a. Build Number.

+
+    A build index on the day represented by ``<date>``.
+
+  The build number is reported by ``vswhere`` as ``installationVersion``.
+  For example, VS 16.11.10 has build number ``16.11.32126.315``.

+
+If the value of ``CMAKE_GENERATOR_INSTANCE`` is not specified explicitly
+by the user or a toolchain file, CMake queries the Visual Studio Installer
+to locate VS instances, chooses one, and sets the variable as a cache entry
+to hold the value persistently.  If an environment variable of the form
+``VS##0COMNTOOLS``, where ``##`` the Visual Studio major version number,
+is set and points to the ``Common7/Tools`` directory within one of the
+VS instances, that instance will be used.  Otherwise, if more than one
+VS instance is installed we do not define which one is chosen by default.

-  Debug and Release variants are found separately.
+This module may set the following variables depending on platform.
+These variables may optionally be set to help this module find the

+
+``GLUT_INCLUDE_DIR``
+  The full path to the directory containing ``GL/glut.h``,

+
+The following variables may also be provided, for backwards compatibility:
+
+``GLUT_INCLUDE_DIR``
+  This is one of above `Cache Variables`_, but prior to CMake 3.23 was

+   * few megabyte, and so that was a security issue.  Hence, a function call
+   * stack is avoided now by resolving recursion.)
+   *
+   * The iterative approach works as follows:
+   *
+   * - We have two writing pointers, both walking up the result array; one does
+   *   the work, the other creates "jobs" for its colleague to do, and leads
+   *   the way:
+   *
+   *   - The faster one, pointer jobDest, always leads and writes "what job
+   *     to do" by the other, once they reach that place in the
+   *     array: leader "jobDest" stores the source node array index (relative
+   *     to array dtd->scaffold) in field "numchildren".
+   *
+   *   - The slower one, pointer dest, looks at the value stored in the
+   *     "numchildren" field (which actually holds a source node array index
+   *     at that time) and puts the real data from dtd->scaffold in.
+   *
+   * - Before the loop starts, jobDest writes source array index 0
+   *   (where the root node is located) so that dest will have something to do
+   *   when it starts operation.
+   *
+   * - Whenever nodes with children are encountered, jobDest appends
+   *   them as new jobs, in order.  As a result, tree node siblings are
+   *   adjacent in the resulting array, for example:
+   *
+   *     [0] root, has two children
+   *       [1] first child of 0, has three children
+   *         [3] first child of 1, does not have children
+   *         [4] second child of 1, does not have children
+   *         [5] third child of 1, does not have children
+   *       [2] second child of 0, does not have children
+   *
+   *   Or (the same data) presented in flat array view:
+   *
+   *     [0] root, has two children
+   *
+   *     [1] first child of 0, has three children
+   *     [2] second child of 0, does not have children
+   *
+   *     [3] first child of 1, does not have children
+   *     [4] second child of 1, does not have children
+   *     [5] third child of 1, does not have children

-The Utilities/cmjsoncpp directory contains a reduced distribution
-of the jsoncpp source tree with only the library source code and
-CMake build system.  It is not a submodule; the actual content is part
-of our source tree and changes can be made and committed directly.
-
-We update from upstream using Git's "subtree" merge strategy.  A
-special branch contains commits of upstream jsoncpp snapshots and
-nothing else.  No Git ref points explicitly to the head of this
-branch, but it is merged into our history.
-
-Update jsoncpp from upstream as follows.  Create a local branch to
-explicitly reference the upstream snapshot branch head:
-
- git branch jsoncpp-upstream 53f6ccb0
-
-Use a temporary directory to checkout the branch:
-
- mkdir jsoncpp-tmp
- cd jsoncpp-tmp
- git init
- git pull .. jsoncpp-upstream
- rm -rf *
-
-Now place the (reduced) jsoncpp content in this directory.  See
-instructions shown by
-
- git log 53f6ccb0
-
-for help extracting the content from the upstream svn repo.  Then run
-the following commands to commit the new version.  Substitute the
-appropriate date and version number:
-
- git add --all
-
- GIT_AUTHOR_NAME='JsonCpp Upstream' \
- GIT_AUTHOR_EMAIL='kwrobot@kitware.com' \
- GIT_AUTHOR_DATE='Thu Nov 20 08:45:58 2014 -0600' \
- git commit -m 'JsonCpp 1.0.0 (reduced)' &&
- git commit --amend
-
-Edit the commit message to describe the procedure used to obtain the
-content.  Then push the changes back up to the main local repository:
-
- git push .. HEAD:jsoncpp-upstream
- cd ..
- rm -rf jsoncpp-tmp
-
-Create a topic in the main repository on which to perform the update:
-
- git checkout -b update-jsoncpp master
-
-Merge the jsoncpp-upstream branch as a subtree:

+Welcome to PDCurses!
+====================
+
+PDCurses is an implementation of X/Open curses for multiple platforms.
+The latest version can be found at:
+
+   https://pdcurses.org/
+
+For changes, see the [History] file. The main documentation is now in
+the [docs] directory.
+
+
+Legal Stuff
+-----------
+
+The core package is in the public domain, but small portions of PDCurses
+are subject to copyright under various licenses.  Each directory
+contains a README.md file, with a section titled "Distribution Status"
+which describes the status of the files in that directory.
+
+If you use PDCurses in an application, an acknowledgement would be
+appreciated, but is not mandatory. If you make corrections or
+enhancements to PDCurses, please forward them to the current maintainer
+for the benefit of other users.
+
+This software is provided AS IS with NO WARRANTY whatsoever.
+
+
+Ports
+-----
+
+PDCurses has been ported to DOS, OS/2, Windows, X11 and SDL. A directory
+containing the port-specific source files exists for each of these
+platforms.
+
+Build instructions are in the README.md file for each platform:
+
+-  [DOS]
+-  [OS/2]
+-  [SDL 1.x]
+-  [SDL 2.x]
+-  [Windows]
+-  [X11]
+
+
+Distribution Status
+-------------------
+
+All files in this directory (not including subdirectories) are released
+to the public domain.

+
+### Description
+
+   addch() adds the chtype ch to the default window (stdscr) at the
+   current cursor position, and advances the cursor. Note that chtypes
+   can convey both text (a single character) and attributes, including a
+   color pair. add_wch() is the wide-character version of this function,
+   taking a pointer to a cchar_t instead of a chtype.
+
+   waddch() is like addch(), but also lets you specify the window. (This
+   is in fact the core output routine.) wadd_wch() is the wide version.
+
+   mvaddch() moves the cursor to the specified (y, x) position, and adds
+   ch to stdscr. mvadd_wch() is the wide version.
+
+   mvwaddch() moves the cursor to the specified position and adds ch to
+   the specified window. mvwadd_wch() is the wide version.
+
+   echochar() adds ch to stdscr at the current cursor position and calls
+   refresh(). echo_wchar() is the wide version.
+
+   wechochar() adds ch to the specified window and calls wrefresh().
+   wecho_wchar() is the wide version.
+
+   addrawch(), waddrawch(), mvaddrawch() and mvwaddrawch() are PDCurses-
+   specific wrappers for addch() etc. that disable the translation of
+   control characters.
+
+   The following applies to all these functions:
+
+   If the cursor moves on to the right margin, an automatic newline is
+   performed. If scrollok is enabled, and a character is added to the
+   bottom right corner of the window, the scrolling region will be
+   scrolled up one line. If scrolling is not allowed, ERR will be
+   returned.
+
+   If ch is a tab, newline, or backspace, the cursor will be moved
+   appropriately within the window. If ch is a newline, the clrtoeol
+   routine is called before the cursor is moved to the beginning of the
+   next line. If newline mapping is off, the cursor will be moved to
+   the next line, but the x coordinate will be unchanged. If ch is a
+   tab the cursor is moved to the next tab position within the window.
+   If ch is another control character, it will be drawn in the ^X
+   notation. Calling the inch() routine after adding a control
+   character returns the representation of the control character, not
+   the control character.
+
+   Video attributes can be combined with a character by ORing them into
+   the parameter. Text, including attributes, can be copied from one
+   place to another by using inch() and addch().
+
+   Note that in PDCurses, for now, a cchar_t and a chtype are the same.
+   The text field is 16 bits wide, and is treated as Unicode (UCS-2)
+   when PDCurses is built with wide-character support (define PDC_WIDE).
+   So, in functions that take a chtype, like addch(), both the wide and
+   narrow versions will handle Unicode. But for portability, you should
+   use the wide functions.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+
+### Description
+
+   These routines write a chtype or cchar_t string directly into the
+   window structure, starting at the current or specified position. The
+   four routines with n as the last argument copy at most n elements,
+   but no more than will fit on the line. If n == -1 then the whole
+   string is copied, up to the maximum number that will fit on the line.
+
+   The cursor position is not advanced. These routines do not check for
+   newline or other special characters, nor does any line wrapping
+   occur.
+
+### Return Value
+
+   All functions return OK or ERR.

+
+### Description
+
+   These routines write all the characters of the null-terminated string
+   str or wide-character string wstr to the given window. The
+   functionality is similar to calling waddch() once for each character
+   in the string; except that, when PDCurses is built with wide-
+   character support enabled, the narrow-character functions treat the
+   string as a multibyte string in the current locale, and convert it.
+   The routines with n as the last argument write at most n characters;
+   if n is negative, then the entire string will be added.

+
+### Description
+
+   These functions manipulate the current attributes and/or colors of
+   the named window. These attributes can be any combination of
+   A_STANDOUT, A_REVERSE, A_BOLD, A_DIM, A_BLINK, A_UNDERLINE. These
+   constants are defined in <curses.h> and can be combined with the
+   bitwise-OR operator (|).
+
+   The current attributes of a window are applied to all chtypes that
+   are written into the window with waddch(). Attributes are a property
+   of the chtype, and move with the character through any scrolling or
+   insert/delete operations.
+
+   wattrset() sets the current attributes of the given window to attrs.
+   attrset() is the stdscr version.
+
+   wattroff() turns off the named attributes without affecting any other
+   attributes; wattron() turns them on.
+
+   wcolor_set() sets the window color to the value of color_pair. opts
+   is unused.
+
+   standout() is the same as attron(A_STANDOUT). standend() is the same
+   as attrset(A_NORMAL); that is, it turns off all attributes.
+
+   The attr_* and wattr_* functions are intended for use with the WA_*
+   attributes. In PDCurses, these are the same as A_*, and there is no
+   difference in bevahior from the chtype-based functions. In all cases,
+   opts is unused.
+
+   wattr_get() retrieves the attributes and color pair for the specified
+   window.
+
+   wchgat() sets the color pair and attributes for the next n cells on
+   the current line of a given window, without changing the existing
+   text, or alterting the window's attributes. An n of -1 extends the
+   change to the edge of the window. The changes take effect
+   immediately. opts is unused.
+
+   wunderscore() turns on the A_UNDERLINE attribute; wunderend() turns
+   it off. underscore() and underend() are the stdscr versions.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+    int wgetbkgrnd(WINDOW *win, cchar_t *wch);
+
+### Description
+
+   bkgdset() and wbkgdset() manipulate the background of a window. The
+   background is a chtype consisting of any combination of attributes
+   and a character; it is combined with each chtype added or inserted to
+   the window by waddch() or winsch(). Only the attribute part is used
+   to set the background of non-blank characters, while both character
+   and attributes are used for blank positions.
+
+   bkgd() and wbkgd() not only change the background, but apply it
+   immediately to every cell in the window.
+
+   wbkgrnd(), wbkgrndset() and wgetbkgrnd() are the "wide-character"
+   versions of these functions, taking a pointer to a cchar_t instead of
+   a chtype. However, in PDCurses, cchar_t and chtype are the same.
+
+   The attributes that are defined with the attrset()/attron() set of
+   functions take precedence over the background attributes if there is
+   a conflict (e.g., different color pairs).
+
+### Return Value
+
+   bkgd() and wbkgd() return OK, unless the window is NULL, in which
+   case they return ERR.

+
+### Description
+
+   border(), wborder(), and box() draw a border around the edge of the
+   window. If any argument is zero, an appropriate default is used:
+
+    ls    left side of border             ACS_VLINE
+    rs    right side of border            ACS_VLINE
+    ts    top side of border              ACS_HLINE
+    bs    bottom side of border           ACS_HLINE
+    tl    top left corner of border       ACS_ULCORNER
+    tr    top right corner of border      ACS_URCORNER
+    bl    bottom left corner of border    ACS_LLCORNER
+    br    bottom right corner of border   ACS_LRCORNER
+
+   hline() and whline() draw a horizontal line, using ch, starting from
+   the current cursor position. The cursor position does not change. The
+   line is at most n characters long, or as many as will fit in the
+   window.
+
+   vline() and wvline() draw a vertical line, using ch, starting from
+   the current cursor position. The cursor position does not change. The
+   line is at most n characters long, or as many as will fit in the
+   window.
+
+   The *_set functions are the "wide-character" versions, taking
+   pointers to cchar_t instead of chtype. Note that in PDCurses, chtype
+   and cchar_t are the same.
+
+### Return Value
+
+   These functions return OK on success and ERR on error.
+
+### Portability

+
+### Description
+
+   erase() and werase() copy blanks (i.e. the background chtype) to

+
+   clear() and wclear() are similar to erase() and werase(), but they
+   also call clearok() to ensure that the the window is cleared on the
+   next wrefresh().
+
+   clrtobot() and wclrtobot() clear the window from the current cursor
+   position to the end of the window.
+
+   clrtoeol() and wclrtoeol() clear the window from the current cursor
+   position to the end of the current line.

+
+    int PDC_set_line_color(short color);
+
+### Description
+
+   To use these routines, first, call start_color(). Colors are always
+   used in pairs, referred to as color-pairs. A color-pair is created by
+   init_pair(), and consists of a foreground color and a background
+   color. After initialization, COLOR_PAIR(n) can be used like any other
+   video attribute.
+
+   has_colors() reports whether the terminal supports color.
+
+   start_color() initializes eight basic colors (black, red, green,
+   yellow, blue, magenta, cyan, and white), and two global variables:
+   COLORS and COLOR_PAIRS (respectively defining the maximum number of
+   colors and color-pairs the terminal is capable of displaying).
+
+   init_pair() changes the definition of a color-pair. It takes three
+   arguments: the number of the color-pair to be redefined, and the new
+   values of the foreground and background colors. The pair number must
+   be between 0 and COLOR_PAIRS - 1, inclusive. The foreground and
+   background must be between 0 and COLORS - 1, inclusive. If the color
+   pair was previously initialized, the screen is refreshed, and all
+   occurrences of that color-pair are changed to the new definition.
+
+   pair_content() is used to determine what the colors of a given color-
+   pair consist of.
+
+   can_change_color() indicates if the terminal has the capability to
+   change the definition of its colors.
+
+   init_color() is used to redefine a color, if possible. Each of the
+   components -- red, green, and blue -- is specified in a range from 0
+   to 1000, inclusive.
+
+   color_content() reports the current definition of a color in the same
+   format as used by init_color().
+
+   assume_default_colors() and use_default_colors() emulate the ncurses
+   extensions of the same names. assume_default_colors(f, b) is
+   essentially the same as init_pair(0, f, b) (which isn't allowed); it
+   redefines the default colors. use_default_colors() allows the use of
+   -1 as a foreground or background color with init_pair(), and calls
+   assume_default_colors(-1, -1); -1 represents the foreground or
+   background color that the terminal had at startup. If the environment
+   variable PDC_ORIGINAL_COLORS is set at the time start_color() is
+   called, that's equivalent to calling use_default_colors().
+
+   alloc_pair(), find_pair() and free_pair() are also from ncurses.
+   free_pair() marks a pair as unused; find_pair() returns an existing
+   pair with the specified foreground and background colors, if one
+   exists. And alloc_pair() returns such a pair whether or not it was
+   previously set, overwriting the oldest initialized pair if there are
+   no free pairs.
+
+   PDC_set_line_color() is used to set the color, globally, for the
+   color of the lines drawn for the attributes: A_UNDERLINE, A_LEFT and
+   A_RIGHT. A value of -1 (the default) indicates that the current
+   foreground color should be used.
+
+   NOTE: COLOR_PAIR() and PAIR_NUMBER() are implemented as macros.
+
+### Return Value
+
+   Most functions return OK on success and ERR on error. has_colors()
+   and can_change_colors() return TRUE or FALSE. alloc_pair() and
+   find_pair() return a pair number, or -1 on error.

+
+### Description
+
+   traceon() and traceoff() toggle the recording of debugging
+   information to the file "trace". Although not standard, similar
+   functions are in some other curses implementations.
+
+   PDC_debug() is the function that writes to the file, based on whether
+   traceon() has been called. It's used from the PDC_LOG() macro.
+
+   The environment variable PDC_TRACE_FLUSH controls whether the trace
+   file contents are fflushed after each write. The default is not. Set
+   it to enable this (may affect performance).

+
+    unsigned long PDC_get_key_modifiers(void);
+    int PDC_return_key_modifiers(bool flag);
+
+### Description
+
+   With the getch(), wgetch(), mvgetch(), and mvwgetch() functions, a
+   character is read from the terminal associated with the window. In
+   nodelay mode, if there is no input waiting, the value ERR is
+   returned. In delay mode, the program will hang until the system
+   passes text through to the program. Depending on the setting of
+   cbreak(), this will be after one character or after the first
+   newline. Unless noecho() has been set, the character will also be
+   echoed into the designated window.
+
+   If keypad() is TRUE, and a function key is pressed, the token for
+   that function key will be returned instead of the raw characters.
+   Possible function keys are defined in <curses.h> with integers
+   beginning with 0401, whose names begin with KEY_.
+
+   If nodelay(win, TRUE) has been called on the window and no input is
+   waiting, the value ERR is returned.
+
+   ungetch() places ch back onto the input queue to be returned by the
+   next call to wgetch().
+
+   flushinp() throws away any type-ahead that has been typed by the user
+   and has not yet been read by the program.
+
+   wget_wch() is the wide-character version of wgetch(), available when
+   PDCurses is built with the PDC_WIDE option. It takes a pointer to a
+   wint_t rather than returning the key as an int, and instead returns
+   KEY_CODE_YES if the key is a function key. Otherwise, it returns OK
+   or ERR. It's important to check for KEY_CODE_YES, since regular wide
+   characters can have the same values as function key codes.
+
+   unget_wch() puts a wide character on the input queue.
+
+   PDC_get_key_modifiers() returns the keyboard modifiers (shift,
+   control, alt, numlock) effective at the time of the last getch()
+   call. Use the macros PDC_KEY_MODIFIER_* to determine which
+   modifier(s) were set. PDC_return_key_modifiers() tells getch() to
+   return modifier keys pressed alone as keystrokes (KEY_ALT_L, etc.).
+   These may not work on all platforms.
+
+   NOTE: getch() and ungetch() are implemented as macros, to avoid
+   conflict with many DOS compiler's runtime libraries.
+
+### Return Value
+
+   These functions return ERR or the value of the character, meta
+   character or function key token.

+    int wget_wstr(WINDOW *win, wint_t *wstr);
+    int mvget_wstr(int y, int x, wint_t *wstr);
+    int mvwget_wstr(WINDOW *win, int, int, wint_t *wstr);
+    int getn_wstr(wint_t *wstr, int n);
+    int wgetn_wstr(WINDOW *win, wint_t *wstr, int n);
+    int mvgetn_wstr(int y, int x, wint_t *wstr, int n);
+    int mvwgetn_wstr(WINDOW *win, int y, int x, wint_t *wstr, int n);
+
+### Description
+
+   These routines call wgetch() repeatedly to build a string,
+   interpreting erase and kill characters along the way, until a newline
+   or carriage return is received. When PDCurses is built with wide-
+   character support enabled, the narrow-character functions convert the
+   wgetch()'d values into a multibyte string in the current locale
+   before returning it. The resulting string is placed in the area
+   pointed to by *str. The routines with n as the last argument read at
+   most n characters.
+
+   Note that there's no way to know how long the buffer passed to
+   wgetstr() is, so use wgetnstr() to avoid buffer overflows.
+
+### Return Value
+
+   These functions return ERR on failure or any other value on success.
+
+### Portability

+    int getparx(WINDOW *win);
+    int getmaxy(WINDOW *win);
+    int getmaxx(WINDOW *win);
+
+### Description
+
+   The getyx() macro (defined in curses.h -- the prototypes here are
+   merely illustrative) puts the current cursor position of the
+   specified window into y and x. getbegyx() and getmaxyx() return the
+   starting coordinates and size of the specified window, respectively.
+   getparyx() returns the starting coordinates of the parent's window,
+   if the specified window is a subwindow; otherwise it sets y and x to
+   -1. These are all macros.
+
+   getsyx() gets the coordinates of the virtual screen cursor, and
+   stores them in y and x. If leaveok() is TRUE, it returns -1, -1. If
+   lines have been removed with ripoffline(), then getsyx() includes
+   these lines in its count; so, the returned y and x values should only
+   be used with setsyx().
+
+   setsyx() sets the virtual screen cursor to the y, x coordinates. If
+   either y or x is -1, leaveok() is set TRUE, else it's set FALSE.
+
+   getsyx() and setsyx() are meant to be used by a library routine that
+   manipulates curses windows without altering the position of the
+   cursor. Note that getsyx() is defined only as a macro.
+
+   getbegy(), getbegx(), getcurx(), getcury(), getmaxy(), getmaxx(),
+   getpary(), and getparx() return the appropriate coordinate or size
+   values, or ERR in the case of a NULL window.

+
+### Description
+
+   The inch() functions retrieve the character and attribute from the
+   current or specified window position, in the form of a chtype. If a
+   NULL window is specified, (chtype)ERR is returned.
+
+   The in_wch() functions are the wide-character versions; instead of
+   returning a chtype, they store a cchar_t at the address specified by
+   wcval, and return OK or ERR. (No value is stored when ERR is
+   returned.) Note that in PDCurses, chtype and cchar_t are the same.

+    WINDOW *Xinitscr(int argc, char **argv);
+    int endwin(void);
+    bool isendwin(void);
+    SCREEN *newterm(const char *type, FILE *outfd, FILE *infd);
+    SCREEN *set_term(SCREEN *new);

+    int resize_term(int nlines, int ncols);
+    bool is_termresized(void);

+    void PDC_get_version(PDC_VERSION *ver);
+
+    int set_tabsize(int tabsize);
+
+### Description
+
+   initscr() should be the first curses routine called. It will
+   initialize all curses data structures, and arrange that the first
+   call to refresh() will clear the screen. In case of error, initscr()
+   will write a message to standard error and end the program.
+
+   endwin() should be called before exiting or escaping from curses mode
+   temporarily. It will restore tty modes, move the cursor to the lower
+   left corner of the screen and reset the terminal into the proper
+   non-visual mode. To resume curses after a temporary escape, call
+   refresh() or doupdate().
+
+   isendwin() returns TRUE if endwin() has been called without a
+   subsequent refresh, unless SP is NULL.
+
+   In some implementations of curses, newterm() allows the use of
+   multiple terminals. Here, it's just an alternative interface for
+   initscr(). It always returns SP, or NULL.
+
+   delscreen() frees the memory allocated by newterm() or initscr(),
+   since it's not freed by endwin(). This function is usually not
+   needed. In PDCurses, the parameter must be the value of SP, and
+   delscreen() sets SP to NULL.
+
+   set_term() does nothing meaningful in PDCurses, but is included for
+   compatibility with other curses implementations.
+
+   resize_term() is effectively two functions: When called with nonzero
+   values for nlines and ncols, it attempts to resize the screen to the
+   given size. When called with (0, 0), it merely adjusts the internal
+   structures to match the current size after the screen is resized by
+   the user. On the currently supported platforms, SDL, Windows console,
+   and X11 allow user resizing, while DOS, OS/2, SDL and Windows console
+   allow programmatic resizing. If you want to support user resizing,
+   you should check for getch() returning KEY_RESIZE, and/or call
+   is_termresized() at appropriate times; if either condition occurs,
+   call resize_term(0, 0). Then, with either user or programmatic
+   resizing, you'll have to resize any windows you've created, as
+   appropriate; resize_term() only handles stdscr and curscr.
+
+   is_termresized() returns TRUE if the curses screen has been resized
+   by the user, and a call to resize_term() is needed. Checking for
+   KEY_RESIZE is generally preferable, unless you're not handling the
+   keyboard.
+
+   curses_version() returns a string describing the version of PDCurses.
+
+   PDC_get_version() fills a PDC_VERSION structure provided by the user
+   with more detailed version info (see curses.h).
+
+   set_tabsize() sets the tab interval, stored in TABSIZE.
+
+### Return Value
+
+   All functions return NULL on error, except endwin(), which always
+   returns OK, and resize_term(), which returns either OK or ERR.

+
+### Description
+
+   cbreak() and nocbreak() toggle cbreak mode. In cbreak mode,
+   characters typed by the user are made available immediately, and
+   erase/kill character processing is not performed. In nocbreak mode,
+   typed characters are buffered until a newline or carriage return.
+   Interrupt and flow control characters are unaffected by this mode.
+   PDCurses always starts in cbreak mode.
+
+   echo() and noecho() control whether typed characters are echoed by
+   the input routine. Initially, input characters are echoed. Subsequent
+   calls to echo() and noecho() do not flush type-ahead.
+
+   halfdelay() is similar to cbreak(), but allows for a time limit to be
+   specified, in tenths of a second. This causes getch() to block for
+   that period before returning ERR if no key has been received. tenths
+   must be between 1 and 255.
+
+   keypad() controls whether getch() returns function/special keys as
+   single key codes (e.g., the left arrow key as KEY_LEFT). Per X/Open,
+   the default for keypad mode is OFF. You'll probably want it on. With
+   keypad mode off, if a special key is pressed, getch() does nothing or
+   returns ERR.
+
+   nodelay() controls whether wgetch() is a non-blocking call. If the
+   option is enabled, and no input is ready, wgetch() will return ERR.
+   If disabled, wgetch() will hang until input is ready.
+
+   nl() enables the translation of a carriage return into a newline on
+   input. nonl() disables this. Initially, the translation does occur.
+
+   raw() and noraw() toggle raw mode. Raw mode is similar to cbreak
+   mode, in that characters typed are immediately passed through to the
+   user program. The difference is that in raw mode, the INTR, QUIT,
+   SUSP, and STOP characters are passed through without being
+   interpreted, and without generating a signal.
+
+   In PDCurses, the meta() function sets raw mode on or off.
+
+   timeout() and wtimeout() set blocking or non-blocking reads for the
+   specified window. If the delay is negative, a blocking read is used;
+   if zero, then non-blocking reads are done -- if no input is waiting,
+   ERR is returned immediately. If the delay is positive, the read
+   blocks for the delay period; if the period expires, ERR is returned.
+   The delay is given in milliseconds, but this is rounded down to 50ms
+   (1/20th sec) intervals, with a minimum of one interval if a postive
+   delay is given; i.e., 1-99 will wait 50ms, 100-149 will wait 100ms,
+   etc.
+
+   intrflush(), notimeout(), noqiflush(), qiflush() and typeahead() do
+   nothing in PDCurses, but are included for compatibility with other
+   curses implementations.
+
+   crmode() and nocrmode() are archaic equivalents to cbreak() and
+   nocbreak(), respectively.
+
+   is_keypad() reports whether the specified window is in keypad mode.
+
+### Return Value
+
+   All functions except is_keypad() and the void functions return OK on
+   success and ERR on error.

+
+### Description
+
+   The insch() functions insert a chtype into the window at the current
+   or specified cursor position. The cursor is NOT advanced. A newline
+   is equivalent to clrtoeol(); tabs are expanded; other control
+   characters are converted as with unctrl().
+
+   The ins_wch() functions are the wide-character equivalents, taking
+   cchar_t pointers rather than chtypes.
+
+   Video attributes can be combined with a character by ORing them into
+   the parameter. Text, including attributes, can be copied from one
+   place to another using inch() and insch().
+
+   insrawch() etc. are PDCurses-specific wrappers for insch() etc. that
+   disable the translation of control characters.
+
+### Return Value
+

+
+### Description
+
+   The insstr() functions insert a character string into a window at the
+   current cursor position, by repeatedly calling winsch(). When
+   PDCurses is built with wide-character support enabled, the narrow-
+   character functions treat the string as a multibyte string in the
+   current locale, and convert it first. All characters to the right of
+   the cursor are moved to the right, with the possibility of the
+   rightmost characters on the line being lost. The cursor position
+   does not change (after moving to y, x, if specified). The routines
+   with n as the last argument insert at most n characters; if n is
+   negative, then the entire string is inserted.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+### Description

+
+### Description
+
+   def_prog_mode() and def_shell_mode() save the current terminal modes
+   as the "program" (in curses) or "shell" (not in curses) state for use
+   by the reset_prog_mode() and reset_shell_mode() functions. This is
+   done automatically by initscr().
+
+   reset_prog_mode() and reset_shell_mode() restore the terminal to
+   "program" (in curses) or "shell" (not in curses) state. These are
+   done automatically by endwin() and doupdate() after an endwin(), so
+   they would normally not be called before these functions.
+
+   savetty() and resetty() save and restore the state of the terminal
+   modes. savetty() saves the current state in a buffer, and resetty()
+   restores the state to what it was at the last call to savetty().
+
+   curs_set() alters the appearance of the cursor. A visibility of 0
+   makes it disappear; 1 makes it appear "normal" (usually an underline)
+   and 2 makes it "highly visible" (usually a block).
+
+   ripoffline() reduces the size of stdscr by one line. If the "line"
+   parameter is positive, the line is removed from the top of the
+   screen; if negative, from the bottom. Up to 5 lines can be ripped off
+   stdscr by calling ripoffline() repeatedly. The function argument,
+   init, is called from within initscr() or newterm(), so ripoffline()
+   must be called before either of these functions. The init function
+   receives a pointer to a one-line WINDOW, and the width of the window.
+   Calling ripoffline() with a NULL init function pointer is an error.
+
+   napms() suspends the program for the specified number of
+   milliseconds. draino() is an archaic equivalent. Note that since
+   napms() attempts to give up a time slice and yield control back to
+   the OS, all times are approximate. (In DOS, the delay is actually
+   rounded down to 50ms (1/20th sec) intervals, with a minimum of one
+   interval; i.e., 1-99 will wait 50ms, 100-149 will wait 100ms, etc.)
+   0 returns immediately.
+
+   resetterm(), fixterm() and saveterm() are archaic equivalents for
+   reset_shell_mode(), reset_prog_mode() and def_prog_mode(),
+   respectively.
+
+### Return Value
+
+   All functions return OK on success and ERR on error, except
+   curs_set(), which returns the previous visibility.

+
+### Description
+
+   As of PDCurses 3.0, there are two separate mouse interfaces: the
+   classic interface, which is based on the undocumented Sys V mouse
+   functions; and an ncurses-compatible interface. Both are active at
+   all times, and you can mix and match functions from each, though it's
+   not recommended. The ncurses interface is essentially an emulation
+   layer built on top of the classic interface; it's here to allow
+   easier porting of ncurses apps.
+
+   The classic interface: mouse_set(), mouse_on(), mouse_off(),
+   request_mouse_pos(), wmouse_position(), and getmouse(). An
+   application using this interface would start by calling mouse_set()
+   or mouse_on() with a non-zero value, often ALL_MOUSE_EVENTS. Then it
+   would check for a KEY_MOUSE return from getch(). If found, it would
+   call request_mouse_pos() to get the current mouse status.
+
+   mouse_set(), mouse_on() and mouse_off() are analagous to attrset(),
+   attron() and attroff(). These functions set the mouse button events
+   to trap. The button masks used in these functions are defined in
+   curses.h and can be or'ed together. They are the group of masks
+   starting with BUTTON1_RELEASED.
+
+   request_mouse_pos() requests curses to fill in the Mouse_status
+   structure with the current state of the mouse.
+
+   wmouse_position() determines if the current mouse position is within
+   the window passed as an argument. If the mouse is outside the current
+   window, -1 is returned in the y and x arguments; otherwise the y and
+   x coordinates of the mouse (relative to the top left corner of the
+   window) are returned in y and x.
+
+   getmouse() returns the current status of the trapped mouse buttons as
+   set by mouse_set() or mouse_on().
+
+   The ncurses interface: mouseinterval(), wenclose(), wmouse_trafo(),
+   mouse_trafo(), mousemask(), nc_getmouse(), ungetmouse() and
+   has_mouse(). A typical application using this interface would start
+   by calling mousemask() with a non-zero value, often ALL_MOUSE_EVENTS.
+   Then it would check for a KEY_MOUSE return from getch(). If found, it
+   would call nc_getmouse() to get the current mouse status.
+
+   mouseinterval() sets the timeout for a mouse click. On all current
+   platforms, PDCurses receives mouse button press and release events,
+   but must synthesize click events. It does this by checking whether a
+   release event is queued up after a press event. If it gets a press
+   event, and there are no more events waiting, it will wait for the
+   timeout interval, then check again for a release. A press followed by
+   a release is reported as BUTTON_CLICKED; otherwise it's passed
+   through as BUTTON_PRESSED. The default timeout is 150ms; valid values
+   are 0 (no clicks reported) through 1000ms. In x11, the timeout can
+   also be set via the clickPeriod resource. The return value from
+   mouseinterval() is the old timeout. To check the old value without
+   setting a new one, call it with a parameter of -1. Note that although
+   there's no classic equivalent for this function (apart from the
+   clickPeriod resource), the value set applies in both interfaces.
+
+   wenclose() reports whether the given screen-relative y, x coordinates
+   fall within the given window.
+
+   wmouse_trafo() converts between screen-relative and window-relative
+   coordinates. A to_screen parameter of TRUE means to convert from
+   window to screen; otherwise the reverse. The function returns FALSE
+   if the coordinates aren't within the window, or if any of the
+   parameters are NULL. The coordinates have been converted when the
+   function returns TRUE.
+
+   mouse_trafo() is the stdscr version of wmouse_trafo().
+
+   mousemask() is nearly equivalent to mouse_set(), but instead of
+   OK/ERR, it returns the value of the mask after setting it. (This
+   isn't necessarily the same value passed in, since the mask could be
+   altered on some platforms.) And if the second parameter is a non-null
+   pointer, mousemask() stores the previous mask value there. Also,
+   since the ncurses interface doesn't work with PDCurses' BUTTON_MOVED
+   events, mousemask() filters them out.
+
+   nc_getmouse() returns the current mouse status in an MEVENT struct.
+   This is equivalent to ncurses' getmouse(), renamed to avoid conflict
+   with PDCurses' getmouse(). But if you define PDC_NCMOUSE before
+   including curses.h, it defines getmouse() to nc_getmouse(), along
+   with a few other redefintions needed for compatibility with ncurses
+   code. nc_getmouse() calls request_mouse_pos(), which (not getmouse())
+   is the classic equivalent.
+
+   ungetmouse() is the mouse equivalent of ungetch(). However, PDCurses
+   doesn't maintain a queue of mouse events; only one can be pushed
+   back, and it can overwrite or be overwritten by real mouse events.
+
+   has_mouse() reports whether the mouse is available at all on the
+   current platform.

+    int wmove(WINDOW *win, int y, int x);
+
+### Description
+
+   move() and wmove() move the cursor associated with the window to the

+### Synopsis
+
+    int clearok(WINDOW *win, bool bf);
+    int idlok(WINDOW *win, bool bf);
+    void idcok(WINDOW *win, bool bf);
+    void immedok(WINDOW *win, bool bf);

+    int setscrreg(int top, int bot);
+    int wsetscrreg(WINDOW *win, int top, int bot);
+    int scrollok(WINDOW *win, bool bf);
+
+    int raw_output(bool bf);
+
+    bool is_leaveok(const WINDOW *win);
+
+### Description
+
+   With clearok(), if bf is TRUE, the next call to wrefresh() with this
+   window will clear the screen completely and redraw the entire screen.
+
+   immedok(), called with a second argument of TRUE, causes an automatic
+   wrefresh() every time a change is made to the specified window.
+
+   Normally, the hardware cursor is left at the location of the window
+   being refreshed. leaveok() allows the cursor to be left wherever the
+   update happens to leave it. It's useful for applications where the
+   cursor is not used, since it reduces the need for cursor motions. If
+   possible, the cursor is made invisible when this option is enabled.
+
+   wsetscrreg() sets a scrolling region in a window; "top" and "bot" are
+   the line numbers for the top and bottom margins. If this option and
+   scrollok() are enabled, any attempt to move off the bottom margin
+   will cause all lines in the scrolling region to scroll up one line.
+   setscrreg() is the stdscr version.
+
+   idlok() and idcok() do nothing in PDCurses, but are provided for
+   compatibility with other curses implementations.
+
+   raw_output() enables the output of raw characters using the standard
+   *add* and *ins* curses functions (that is, it disables translation of
+   control characters).
+
+   is_leaveok() reports whether the specified window is in leaveok mode.
+
+### Return Value
+
+   All functions except is_leaveok() return OK on success and ERR on
+   error.

+    int overwrite(const WINDOW *src_w, WINDOW *dst_w)
+    int copywin(const WINDOW *src_w, WINDOW *dst_w, int src_tr,

+                int dst_bc, int _overlay)
+
+### Description
+
+   overlay() and overwrite() copy all the text from src_w into dst_w.
+   The windows need not be the same size. Those characters in the source
+   window that intersect with the destination window are copied, so that
+   the characters appear in the same physical position on the screen.
+   The difference between the two functions is that overlay() is non-
+   destructive (blanks are not copied) while overwrite() is destructive
+   (blanks are copied).
+
+   copywin() is similar, but doesn't require that the two windows
+   overlap. The arguments src_tc and src_tr specify the top left corner
+   of the region to be copied. dst_tc, dst_tr, dst_br, and dst_bc
+   specify the region within the destination window to copy to. The
+   argument "overlay", if TRUE, indicates that the copy is done non-
+   destructively (as in overlay()); blanks in the source window are not
+   copied to the destination window. When overlay is FALSE, blanks are
+   copied.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+
+### Description
+
+   A pad is a special kind of window, which is not restricted by the
+   screen size, and is not necessarily associated with a particular part
+   of the screen. You can use a pad when you need a large window, and
+   only a part of the window will be on the screen at one time. Pads are
+   not refreshed automatically (e.g., from scrolling or echoing of
+   input). You can't call wrefresh() with a pad as an argument; use
+   prefresh() or pnoutrefresh() instead. Note that these routines
+   require additional parameters to specify the part of the pad to be
+   displayed, and the location to use on the screen.
+
+   newpad() creates a new pad data structure.
+
+   subpad() creates a new sub-pad within a pad, at position (begy,
+   begx), with dimensions of nlines lines and ncols columns. This
+   position is relative to the pad, and not to the screen as with
+   subwin. Changes to either the parent pad or sub-pad will affect both.
+   When using sub-pads, you may need to call touchwin() before calling
+   prefresh().
+
+   pnoutrefresh() copies the specified pad to the virtual screen.
+
+   prefresh() calls pnoutrefresh(), followed by doupdate().
+
+   These routines are analogous to wnoutrefresh() and wrefresh(). (py,
+   px) specifies the upper left corner of the part of the pad to be
+   displayed; (sy1, sx1) and (sy2, sx2) describe the screen rectangle
+   that will contain the selected part of the pad.
+
+   pechochar() is functionally equivalent to addch() followed by a call
+   to prefresh(), with the last-used coordinates and dimensions.
+   pecho_wchar() is the wide-character version.
+
+   is_pad() reports whether the specified window is a pad.
+
+### Return Value
+
+   All functions except is_pad() return OK on success and ERR on error.

+
+### Description
+
+   For historic reasons, and for compatibility with other versions of
+   curses, the panel functions are prototyped in a separate header,
+   panel.h. In many implementations, they're also in a separate library,
+   but PDCurses incorporates them.
+
+   The panel functions provide a way to have depth relationships between
+   curses windows. Panels can overlap without making visible the
+   overlapped portions of underlying windows. The initial curses window,
+   stdscr, lies beneath all panels. The set of currently visible panels
+   is the 'deck' of panels.
+
+   You can create panels, fetch and set their associated windows,
+   shuffle panels in the deck, and manipulate them in other ways.
+
+   bottom_panel() places pan at the bottom of the deck. The size,
+   location and contents of the panel are unchanged.
+
+   del_panel() deletes pan, but not its associated winwow.
+
+   hide_panel() removes a panel from the deck and thus hides it from
+   view.
+
+   move_panel() moves the curses window associated with pan, so that its
+   upper lefthand corner is at the supplied coordinates. (Don't use
+   mvwin() on the window.)
+
+   new_panel() creates a new panel associated with win and returns the
+   panel pointer. The new panel is placed at the top of the deck.
+
+   panel_above() returns a pointer to the panel in the deck above pan,
+   or NULL if pan is the top panel. If the value of pan passed is NULL,
+   this function returns a pointer to the bottom panel in the deck.
+
+   panel_below() returns a pointer to the panel in the deck below pan,
+   or NULL if pan is the bottom panel. If the value of pan passed is
+   NULL, this function returns a pointer to the top panel in the deck.
+
+   panel_hidden() returns OK if pan is hidden and ERR if it is not.
+
+   panel_userptr() - Each panel has a user pointer available for
+   maintaining relevant information. This function returns a pointer to
+   that information previously set up by set_panel_userptr().
+
+   panel_window() returns a pointer to the curses window associated with
+   the panel.
+
+   replace_panel() replaces the current window of pan with win.
+
+   set_panel_userptr() - Each panel has a user pointer available for
+   maintaining relevant information. This function sets the value of
+   that information.
+
+   show_panel() makes a previously hidden panel visible and places it
+   back in the deck on top.
+
+   top_panel() places pan on the top of the deck. The size, location and
+   contents of the panel are unchanged.
+
+   update_panels() refreshes the virtual screen to reflect the depth
+   relationships between the panels in the deck. The user must use
+   doupdate() to refresh the physical screen.
+
+### Return Value
+
+   Each routine that returns a pointer to an object returns NULL if an
+   error occurs. Each panel routine that returns an integer, returns OK
+   if it executes successfully and ERR if it does not.

+printw
+------
+
+### Synopsis
+
+    int printw(const char *fmt, ...);
+    int wprintw(WINDOW *win, const char *fmt, ...);
+    int mvprintw(int y, int x, const char *fmt, ...);
+    int mvwprintw(WINDOW *win, int y, int x, const char *fmt,...);
+    int vwprintw(WINDOW *win, const char *fmt, va_list varglist);
+    int vw_printw(WINDOW *win, const char *fmt, va_list varglist);
+
+### Description
+
+   The printw() functions add a formatted string to the window at the
+   current or specified cursor position. The format strings are the same
+   as used in the standard C library's printf(). (printw() can be used
+   as a drop-in replacement for printf().)
+
+   The duplication between vwprintw() and vw_printw() is for historic
+   reasons. In PDCurses, they're the same.
+
+### Return Value
+
+   All functions return the number of characters printed, or ERR on
+   error.
+
+### Portability
+                             X/Open  ncurses  NetBSD

+### Synopsis
+
+    int refresh(void);
+    int wrefresh(WINDOW *win);
+    int wnoutrefresh(WINDOW *win);
+    int doupdate(void);
+    int redrawwin(WINDOW *win);
+    int wredrawln(WINDOW *win, int beg_line, int num_lines);
+
+### Description
+
+   wrefresh() copies the named window to the physical terminal screen,
+   taking into account what is already there in order to optimize cursor
+   movement. refresh() does the same, using stdscr. These routines must
+   be called to get any output on the terminal, as other routines only
+   manipulate data structures. Unless leaveok() has been enabled, the
+   physical cursor of the terminal is left at the location of the
+   window's cursor.
+
+   wnoutrefresh() and doupdate() allow multiple updates with more
+   efficiency than wrefresh() alone. wrefresh() works by first calling
+   wnoutrefresh(), which copies the named window to the virtual screen.
+   It then calls doupdate(), which compares the virtual screen to the
+   physical screen and does the actual update. A series of calls to
+   wrefresh() will result in alternating calls to wnoutrefresh() and
+   doupdate(), causing several bursts of output to the screen. By first
+   calling wnoutrefresh() for each window, it is then possible to call
+   doupdate() only once.
+
+   In PDCurses, redrawwin() is equivalent to touchwin(), and wredrawln()
+   is the same as touchline(). In some other curses implementations,
+   there's a subtle distinction, but it has no meaning in PDCurses.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+### Synopsis
+
+    int scanw(const char *fmt, ...);
+    int wscanw(WINDOW *win, const char *fmt, ...);
+    int mvscanw(int y, int x, const char *fmt, ...);
+    int mvwscanw(WINDOW *win, int y, int x, const char *fmt, ...);
+    int vwscanw(WINDOW *win, const char *fmt, va_list varglist);
+    int vw_scanw(WINDOW *win, const char *fmt, va_list varglist);
+
+### Description
+
+   These routines correspond to the standard C library's scanf() family.
+   Each gets a string from the window via wgetnstr(), and uses the
+   resulting line as input for the scan.
+
+   The duplication between vwscanw() and vw_scanw() is for historic
+   reasons. In PDCurses, they're the same.
+
+### Return Value
+
+   On successful completion, these functions return the number of items
+   successfully matched. Otherwise they return ERR.
+
+### Portability

+scr_dump
+--------
+
+### Synopsis
+
+    int putwin(WINDOW *win, FILE *filep);
+    WINDOW *getwin(FILE *filep);
+    int scr_dump(const char *filename);
+    int scr_init(const char *filename);
+    int scr_restore(const char *filename);
+    int scr_set(const char *filename);
+
+### Description
+
+   getwin() reads window-related data previously stored in a file by
+   putwin(). It then creates and initialises a new window using that
+   data.
+
+   putwin() writes all data associated with a window into a file, using
+   an unspecified format. This information can be retrieved later using
+   getwin().
+
+   scr_dump() writes the current contents of the virtual screen to the
+   file named by filename in an unspecified format.
+
+   scr_restore() function sets the virtual screen to the contents of the
+   file named by filename, which must have been written using
+   scr_dump(). The next refresh operation restores the screen to the way
+   it looked in the dump file.
+
+   In PDCurses, scr_init() does nothing, and scr_set() is a synonym for
+   scr_restore(). Also, scr_dump() and scr_restore() save and load from
+   curscr. This differs from some other implementations, where
+   scr_init() works with curscr, and scr_restore() works with newscr;
+   but the effect should be the same. (PDCurses has no newscr.)
+
+### Return Value
+
+   On successful completion, getwin() returns a pointer to the window it
+   created. Otherwise, it returns a null pointer. Other functions return
+   OK or ERR.
+
+### Portability

+### Synopsis
+
+    int scroll(WINDOW *win);
+    int scrl(int n);
+    int wscrl(WINDOW *win, int n);
+
+### Description
+
+   scroll() causes the window to scroll up one line. This involves
+   moving the lines in the window data strcture.

+   With a positive n, scrl() and wscrl() scroll the window up n lines
+   (line i + n becomes i); otherwise they scroll the window down n
+   lines.
+
+   For these functions to work, scrolling must be enabled via
+   scrollok(). Note also that scrolling is not allowed if the supplied
+   window is a pad.

+
+### Description
+
+   These functions manipulate a window that contain Soft Label Keys
+   (SLK). To use the SLK functions, a call to slk_init() must be made
+   BEFORE initscr() or newterm(). slk_init() removes 1 or 2 lines from
+   the useable screen, depending on the format selected.
+
+   The line(s) removed from the screen are used as a separate window, in
+   which SLKs are displayed.
+
+   slk_init() requires a single parameter which describes the format of
+   the SLKs as follows:
+
+   0       3-2-3 format
+   1       4-4 format
+   2       4-4-4 format (ncurses extension)
+   3       4-4-4 format with index line (ncurses extension)
+   2 lines used
+   55      5-5 format (pdcurses format)
+
+   slk_refresh(), slk_noutrefresh() and slk_touch() are analogous to
+   refresh(), noutrefresh() and touch().
+
+### Return Value
+
+   All functions return OK on success and ERR on error.
+
+### Portability

+
+### Description
+
+   baudrate() is supposed to return the output speed of the terminal. In
+   PDCurses, it simply returns INT_MAX.
+
+   has_ic and has_il() return TRUE. These functions have meaning in some
+   other implementations of curses.
+
+   erasechar() and killchar() return ^H and ^U, respectively -- the
+   ERASE and KILL characters. In other curses implementations, these may
+   vary by terminal type. erasewchar() and killwchar() are the wide-
+   character versions; they take a pointer to a location in which to
+   store the character, and return OK or ERR.
+
+   longname() returns a pointer to a static area containing a verbose
+   description of the current terminal. The maximum length of the string
+   is 128 characters. It is defined only after the call to initscr() or
+   newterm().
+
+   termname() returns a pointer to a static area containing a short
+   description of the current terminal (14 characters).
+
+   termattrs() returns a logical OR of all video attributes supported by
+   the terminal.
+
+   wordchar() is a PDCurses extension of the concept behind the
+   functions erasechar() and killchar(), returning the "delete word"
+   character, ^W.

+
+    int touchoverlap(const WINDOW *win1, WINDOW *win2);
+
+### Description
+
+   touchwin() and touchline() throw away all information about which
+   parts of the window have been touched, pretending that the entire
+   window has been drawn on. This is sometimes necessary when using
+   overlapping windows, since a change to one window will affect the
+   other window, but the records of which lines have been changed in the
+   other window will not reflect the change.
+
+   untouchwin() marks all lines in the window as unchanged since the
+   last call to wrefresh().
+
+   wtouchln() makes n lines in the window, starting at line y, look as
+   if they have (changed == 1) or have not (changed == 0) been changed
+   since the last call to wrefresh().
+
+   is_linetouched() returns TRUE if the specified line in the specified
+   window has been changed since the last call to wrefresh().
+
+   is_wintouched() returns TRUE if the specified window has been changed
+   since the last call to wrefresh().
+
+   touchoverlap(win1, win2) marks the portion of win2 which overlaps
+   with win1 as modified.
+
+### Return Value
+
+   All functions return OK on success and ERR on error except
+   is_wintouched() and is_linetouched().

+    size_t PDC_wcstombs(char *dest, const wchar_t *src, size_t n);
+
+### Description
+
+   unctrl() expands the text portion of the chtype c into a printable
+   string. Control characters are changed to the "^X" notation; others
+   are passed through. wunctrl() is the wide-character version of the
+   function.
+
+   filter() and use_env() are no-ops in PDCurses.
+
+   delay_output() inserts an ms millisecond pause in output.
+
+   getcchar() works in two modes: When wch is not NULL, it reads the
+   cchar_t pointed to by wcval and stores the attributes in attrs, the
+   color pair in color_pair, and the text in the wide-character string
+   wch. When wch is NULL, getcchar() merely returns the number of wide
+   characters in wcval. In either mode, the opts argument is unused.
+
+   setcchar constructs a cchar_t at wcval from the wide-character text
+   at wch, the attributes in attr and the color pair in color_pair. The
+   opts argument is unused.
+
+   Currently, the length returned by getcchar() is always 1 or 0.
+   Similarly, setcchar() will only take the first wide character from
+   wch, and ignore any others that it "should" take (i.e., combining
+   characters). Nor will it correctly handle any character outside the
+   basic multilingual plane (UCS-2).
+
+### Return Value
+
+   wunctrl() returns NULL on failure. delay_output() always returns OK.
+
+   getcchar() returns the number of wide characters wcval points to when
+   wch is NULL; when it's not, getcchar() returns OK or ERR.
+
+   setcchar() returns OK or ERR.

+
+### Description
+
+   newwin() creates a new window with the given number of lines, nlines
+   and columns, ncols. The upper left corner of the window is at line
+   begy, column begx. If nlines is zero, it defaults to LINES - begy;
+   ncols to COLS - begx. Create a new full-screen window by calling
+   newwin(0, 0, 0, 0).
+
+   delwin() deletes the named window, freeing all associated memory. In
+   the case of overlapping windows, subwindows should be deleted before
+   the main window.
+
+   mvwin() moves the window so that the upper left-hand corner is at
+   position (y,x). If the move would cause the window to be off the
+   screen, it is an error and the window is not moved. Moving subwindows
+   is allowed.
+
+   subwin() creates a new subwindow within a window. The dimensions of
+   the subwindow are nlines lines and ncols columns. The subwindow is at
+   position (begy, begx) on the screen. This position is relative to the
+   screen, and not to the window orig. Changes made to either window
+   will affect both. When using this routine, you will often need to
+   call touchwin() before calling wrefresh().
+
+   derwin() is the same as subwin(), except that begy and begx are
+   relative to the origin of the window orig rather than the screen.
+   There is no difference between subwindows and derived windows.
+
+   mvderwin() moves a derived window (or subwindow) inside its parent
+   window. The screen-relative parameters of the window are not changed.
+   This routine is used to display different parts of the parent window
+   at the same physical position on the screen.
+
+   dupwin() creates an exact duplicate of the window win.
+
+   wsyncup() causes a touchwin() of all of the window's parents.
+
+   If wsyncok() is called with a second argument of TRUE, this causes a
+   wsyncup() to be called every time the window is changed.
+
+   wcursyncup() causes the current cursor position of all of a window's
+   ancestors to reflect the current cursor position of the current
+   window.
+
+   wsyncdown() causes a touchwin() of the current window if any of its
+   parent's windows have been touched.
+
+   resize_window() allows the user to resize an existing window. It
+   returns the pointer to the new window, or NULL on failure.
+
+   wresize() is an ncurses-compatible wrapper for resize_window(). Note
+   that, unlike ncurses, it will NOT process any subwindows of the
+   window. (However, you still can call it _on_ subwindows.) It returns
+   OK or ERR.
+
+   PDC_makenew() allocates all data for a new WINDOW * except the actual
+   lines themselves. If it's unable to allocate memory for the window
+   structure, it will free all allocated memory and return a NULL
+   pointer.
+
+   PDC_makelines() allocates the memory for the lines.
+
+   PDC_sync() handles wrefresh() and wsyncup() calls when a window is
+   changed.
+
+### Return Value
+
+   newwin(), subwin(), derwin() and dupwin() return a pointer to the new
+   window, or NULL on failure. delwin(), mvwin(), mvderwin() and
+   syncok() return OK or ERR. wsyncup(), wcursyncup() and wsyncdown()
+   return nothing.
+
+### Errors
+
+   It is an error to call resize_window() before calling initscr().
+   Also, an error will be generated if we fail to create a newly sized
+   replacement window for curscr, or stdscr. This could happen when
+   increasing the window size. NOTE: If this happens, the previously
+   successfully allocated windows are left alone; i.e., the resize is
+   NOT cancelled for those windows.

+PDCurses for Windows console
+============================
+
+This directory contains PDCurses source code files specific to the
+Microsoft Windows console. Although historically called "Win32", this
+port can just as easily be built for 64-bit systems. Windows 95 through
+Windows 10 are covered. (Some features require later versions.)
+
+
+Building
+--------
+
+- Choose the appropriate makefile for your compiler:
+
+        Makefile      - GCC (MinGW or Cygnus)
+        Makefile.bcc  - Borland C++
+        Makefile.vc   - Microsoft Visual C++
+        Makefile.wcc  - Watcom
+
+- Optionally, you can build in a different directory than the platform
+  directory by setting PDCURSES_SRCDIR to point to the directory where
+  you unpacked PDCurses, and changing to your target directory:
+
+        set PDCURSES_SRCDIR=c:\pdcurses
+
+- Build it:
+
+        make -f makefilename
+
+  (For Watcom, use "wmake" instead of "make"; for MSVC, "nmake"; for
+  MinGW, "mingw32-make".) You'll get the library (pdcurses.lib or .a,
+  depending on your compiler) and a lot of object files.
+
+  You can also give the optional parameter "WIDE=Y", to build the
+  library with wide-character (Unicode) support:
+
+        wmake -f Makefile.wcc WIDE=Y
+
+  When built this way, the library is not compatible with Windows 9x,
+  unless you also link with the Microsoft Layer for Unicode (not
+  tested).
+
+  Another option, "UTF8=Y", makes PDCurses ignore the system locale, and
+  treat all narrow-character strings as UTF-8. This option has no effect
+  unless WIDE=Y is also set. Use it to get around the poor support for
+  UTF-8 in the Windows console:
+
+        make -f Makefile.bcc WIDE=Y UTF8=Y
+
+  You can also use the optional parameter "DLL=Y" with Visual C++,
+  MinGW or Cygwin, to build the library as a DLL:
+
+        nmake -f Makefile.vc WIDE=Y DLL=Y
+
+  When you build the library as a Windows DLL, you must always define
+  PDC_DLL_BUILD when linking against it. (Or, if you only want to use
+  the DLL, you could add this definition to your curses.h.)
+
+  Add the target "demos" to build the sample programs.
+
+- If your build stops with errors about PCONSOLE_SCREEN_BUFFER_INFOEX,
+  add the parameter "INFOEX=N" to your make command line and try again.
+  (This will happen with older compile environments.)
+
+
+Distribution Status
+-------------------
+
+The files in this directory are released to the public domain.

+---------
+
+### Synopsis
+
+    int PDC_getclipboard(char **contents, long *length);
+    int PDC_setclipboard(const char *contents, long length);
+    int PDC_freeclipboard(char *contents);
+    int PDC_clearclipboard(void);
+
+### Description
+
+   PDC_getclipboard() gets the textual contents of the system's
+   clipboard. This function returns the contents of the clipboard in the
+   contents argument. It is the responsibility of the caller to free the
+   memory returned, via PDC_freeclipboard(). The length of the clipboard
+   contents is returned in the length argument.
+
+   PDC_setclipboard copies the supplied text into the system's
+   clipboard, emptying the clipboard prior to the copy.
+
+   PDC_clearclipboard() clears the internal clipboard.
+
+### Return Values
+
+   indicator of success/failure of call.
+   PDC_CLIP_SUCCESS        the call was successful
+   PDC_CLIP_MEMORY_ERROR   unable to allocate sufficient memory for
+                           the clipboard contents
+   PDC_CLIP_EMPTY          the clipboard contains no text
+   PDC_CLIP_ACCESS_ERROR   no clipboard support
+
+### Portability

+### Synopsis
+
+    int PDC_set_blink(bool blinkon);
+    int PDC_set_bold(bool boldon);
+    void PDC_set_title(const char *title);
+
+### Description
+
+   PDC_set_blink() toggles whether the A_BLINK attribute sets an actual
+   blink mode (TRUE), or sets the background color to high intensity
+   (FALSE). The default is platform-dependent (FALSE in most cases). It
+   returns OK if it could set the state to match the given parameter,
+   ERR otherwise.
+
+   PDC_set_bold() toggles whether the A_BOLD attribute selects an actual
+   bold font (TRUE), or sets the foreground color to high intensity
+   (FALSE). It returns OK if it could set the state to match the given
+   parameter, ERR otherwise.
+
+   PDC_set_title() sets the title of the window in which the curses
+   program is running. This function may not do anything on some
+   platforms.
+
+### Portability
+                             X/Open  ncurses  NetBSD
