+Compiler id for IBM Clang-based XL compilers is now ``XLClang``.

+CMake 3.15 and above recognize that IBM's Clang-based XL compilers

+with a different command line and set of capabilities.
+CMake now prefers to present this to projects by setting the
+:variable:`CMAKE_<LANG>_COMPILER_ID` variable to ``XLClang`` instead
+of ``XL``.  However, existing projects may assume the compiler id for
+Clang-based XL is just ``XL`` as it was in CMake versions prior to 3.15.
+Therefore this policy determines for Clang-based XL compilers 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

+
+MSVC runtime library flags are selected by an abstraction.
+
+Compilers targeting the MSVC ABI have flags to select the MSVC runtime library.
+Runtime library selection typically varies with build configuration because
+there is a separate runtime library for Debug builds.
+
+In CMake 3.14 and below, MSVC runtime library selection flags are added to
+the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` cache entries by CMake
+automatically.  This allows users to edit their cache entries to adjust the
+flags.  However, the presence of such default flags is problematic for
+projects that want to choose a different runtime library programmatically.
+In particular, it requires string editing of the
+:variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` variables with knowledge of the
+CMake builtin defaults so they can be replaced.
+
+CMake 3.15 and above prefer to leave the MSVC runtime library selection flags
+out of the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` values and instead
+offer a first-class abstraction.  The :variable:`CMAKE_MSVC_RUNTIME_LIBRARY`
+variable and :prop_tgt:`MSVC_RUNTIME_LIBRARY` target property may be set to
+select the MSVC runtime library.
+
+This policy provides compatibility with projects that have not been updated
+to be aware of the abstraction.  The policy setting takes effect as of the
+first :command:`project` or :command:`enable_language` command that enables
+a language whose compiler targets the MSVC ABI.
+
+.. note::
+
+  Once the policy has taken effect at the top of a project, that choice
+  must be used throughout the tree.  In projects that have nested projects
+  in subdirectories, be sure to convert everything together.
+
+The ``OLD`` behavior for this policy is to place MSVC runtime library
+flags in the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` cache
+entries and ignore the :variable:`CMAKE_MSVC_RUNTIME_LIBRARY` abstraction.
+The ``NEW`` behavior for this policy is to *not* place MSVC runtime
+library flags in the default cache entries and use the abstraction instead.
+
+This policy was introduced in CMake version 3.15.  Use the
+:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.

+VS_NO_SOLUTION_DEPLOY
+---------------------
+
+Specify that the target should not be marked for deployment to a Windows CE
+or Windows Phone device in the generated Visual Studio solution.
+
+Be default, all EXE and shared library (DLL) targets are marked to deploy to
+the target device in the generated Visual Studio solution.
+
+Generator expressions are supported.
+
+There are reasons one might want to exclude a target / generated project from
+deployment:
+
+- The library or executable may not be necessary in the primary deploy/debug
+  scenario, and excluding from deployment saves time in the
+  develop/download/debug cycle.
+- There may be insufficient space on the target device to accommodate all of
+  the build products.
+- Visual Studio 2013 requires a target device IP address be entered for each
+  target marked for deployment.  For large numbers of targets, this can be
+  tedious.
+  NOTE: Visual Studio *will* deploy all project dependencies of a project
+  tagged for deployment to the IP address configured for that project even
+  if those dependencies are not tagged for deployment.
+
+
+Example 1
+^^^^^^^^^
+
+This shows setting the variable for the target foo.
+
+.. code-block:: cmake
+
+  add_library(foo SHARED foo.cpp)
+  set_property(TARGET foo PROPERTY VS_NO_SOLUTION_DEPLOY ON)

+FindEnvModules
+--------------
+
+Locate an environment module implementation and make commands available to
+CMake scripts to use them.  This is compatible with both Lua-based Lmod
+and TCL-based EnvironmentModules.
+
+This module is intended for the use case of setting up the compiler and library
+environment within a :ref:`CTest Script <CTest Script>` (``ctest -S``).  It can
+also be used in a :ref:`CMake Script <Script Processing Mode>` (``cmake -P``).
+
+.. note::
+
+  The loaded environment will not survive past the end of the calling process.
+  Do not use this module in project code (``CMakeLists.txt`` files) to load
+  a compiler environment; it will not be available during the build.  Instead
+  load the environment manually before running CMake or using the generated
+  build system.
+
+Example Usage
+^^^^^^^^^^^^^
+
+.. code-block:: cmake
+
+  set(CTEST_BUILD_NAME "CrayLinux-CrayPE-Cray-dynamic")
+  set(CTEST_BUILD_CONFIGURATION Release)
+  set(CTEST_BUILD_FLAGS "-k -j8")
+  set(CTEST_CMAKE_GENERATOR "Unix Makefiles")
+
+  ...
+
+  find_package(EnvModules REQUIRED)
+
+  env_module(purge)
+  env_module(load modules)
+  env_module(load craype)
+  env_module(load PrgEnv-cray)
+  env_module(load craype-knl)
+  env_module(load cray-mpich)
+  env_module(load cray-libsci)
+
+  set(ENV{CRAYPE_LINK_TYPE} dynamic)
+
+  ...
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``EnvModules_FOUND``
+  Found the a compatible environment modules framework
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variable will be set:
+
+``EnvModules_COMMAND``
+  The low level module command to use.  Currently supported are
+  implementations are the Lua based Lmod and TCL based EnvironmentModules.
+
+Environment Variables
+^^^^^^^^^^^^^^^^^^^^^
+
+``ENV{MODULESHOME}``
+  Usually set by the module environment implementation, used as a hint to
+  locate the module command to execute.
+
+Provided Functions
+^^^^^^^^^^^^^^^^^^
+
+This defines the following cmake functions for interacting with environment
+modules:
+
+.. command:: env_module
+
+  Execute an aribitrary module command:
+
+  .. code-block:: cmake
+
+    env_module(cmd arg1 ... argN)
+    env_module(
+      COMMAND cmd arg1 ... argN
+      [OUTPUT_VARIABLE <out-var>]
+      [RESULT_VARIABLE <ret-var>]
+    )
+
+  The options are:
+
+  ``cmd arg1 ... argN``
+    The module sub-command and arguments to execute as if they were
+    passed directly to the module command in your shell environment.
+
+  ``OUTPUT_VARIABLE <out-var>``
+    The standard output from executing the module command.
+
+  ``RESULT_VARIABLE <ret-var>``
+    The return code from executing the module command.
+
+.. command:: env_module_swap
+
+  Swap one module for another:
+
+  .. code-block:: cmake
+
+    env_module_swap(out_mod in_mod
+      [OUTPUT_VARIABLE <out-var>]
+      [RESULT_VARIABLE <ret-var>]
+    )
+
+  This is functionally equivalent to the ``module swap out_mod in_mod`` shell
+  command.  The options are:
+
+  ``OUTPUT_VARIABLE <out-var>``
+    The standard output from executing the module command.
+
+  ``RESULT_VARIABLE <ret-var>``
+    The return code from executing the module command.
+
+.. command:: env_module_list
+
+  Retrieve the list of currently loaded modules:
+
+  .. code-block:: cmake
+
+    env_module_list(<out-var>)
+
+  This is functionally equivalent to the ``module list`` shell command.
+  The result is stored in ``<out-var>`` as a properly formatted CMake
+  :ref:`semicolon-separated list <CMake Language Lists>` variable.
+
+.. command:: env_module_avail
+
+  Retrieve the list of available modules:
+
+  .. code-block:: cmake
+
+    env_module_avail([<mod-prefix>] <out-var>)
+
+  This is functionally equivalent to the ``module avail <mod-prefix>`` shell
+  command.  The result is stored in ``<out-var>`` as a properly formatted
+  CMake :ref:`semicolon-separated list <CMake Language Lists>` variable.

+1. Compile with MSVC from VS 2015 or later.
+   You need to download and install a binary release of CMake.  You can get

+
+2. Bootstrap with MinGW under MSYS2.
+   Download and install `MSYS2`_.  Then install the required build tools::
+
+     $ pacman -S --needed git base-devel mingw-w64-x86_64-gcc
+
+   and bootstrap as above.

-/* cmCommandArgumentsHelper, cmCommandArgumentGroup and cmCommandArgument (i.e.
-its derived classes cmCAXXX can be used to simplify the processing of
-arguments to cmake commands. Maybe they can also be used to generate
-documentation.
-
-For every argument supported by a command one cmCommandArgument is created
-and added to cmCommandArgumentsHelper. cmCommand has a cmCommandArgumentsHelper
-as member variable so this should be used.
-
-The order of the arguments is defined using the Follows(arg) method. It says
-that this argument follows immediateley the given argument. It can be used
-with multiple arguments if the argument can follow after different arguments.
-
-Arguments can be arranged in groups using cmCommandArgumentGroup. Every
-member of a group can follow any other member of the group. These groups
-can also be used to define the order.
-
-Once all arguments and groups are set up, cmCommandArgumentsHelper::Parse()
-is called and afterwards the values of the arguments can be evaluated.
-
-For an example see cmExportCommand.cxx.

-/*-
- * Algorithm from "A Technique for High Performance Data Compression",
- * Terry A. Welch, IEEE Computer Vol 17, No 6 (June 1984), pp 8-19.
- *
- * Usage: compress [-dfvc] [-b bits] [file ...]
- * Inputs:
- *	-d:	    If given, decompression is done instead.
- *
- *      -c:         Write output on stdout, don't remove original.
- *
- *      -b:         Parameter limits the max number of bits/code.
- *
- *	-f:	    Forces output file to be generated, even if one already
- *		    exists, and even if no space is saved by compressing.
- *		    If -f is not used, the user will be prompted if stdin is
- *		    a tty, otherwise, the output file will not be overwritten.
- *
- *      -v:	    Write compression statistics
- *
- * 	file ...:   Files to be compressed.  If none specified, stdin
- *		    is used.
- * Outputs:
- *	file.Z:	    Compressed form of file with same mode, owner, and utimes
- * 	or stdout   (if stdin used as input)
- *
- * Assumptions:
- *	When filenames are given, replaces with the compressed version
- *	(.Z suffix) only if the file decreases in size.
- * Algorithm:
- * 	Modified Lempel-Ziv method (LZW).  Basically finds common
- * substrings and replaces them with a variable size code.  This is
- * deterministic, and can be done on the fly.  Thus, the decompression
- * procedure needs no input table, but tracks the way the table was built.

+
+__Zstandard__, or `zstd` as short version, is a fast lossless compression algorithm,
+targeting real-time compression scenarios at zlib-level and better compression ratios.
+It's backed by a very fast entropy stage, provided by [Huff0 and FSE library](https://github.com/Cyan4973/FiniteStateEntropy).
+
+The project is provided as an open-source dual [BSD](LICENSE) and [GPLv2](COPYING) licensed **C** library,
+and a command line utility producing and decoding `.zst`, `.gz`, `.xz` and `.lz4` files.
+Should your project require another programming language,
+a list of known ports and bindings is provided on [Zstandard homepage](http://www.zstd.net/#other-languages).

+## Benchmarks
+
+For reference, several fast compression algorithms were tested and compared
+on a server running Linux Debian (`Linux version 4.14.0-3-amd64`),
+with a Core i7-6700K CPU @ 4.0GHz,
+using [lzbench], an open-source in-memory benchmark by @inikep
+compiled with [gcc] 7.3.0,
+on the [Silesia compression corpus].

+
+Zstd can also offer stronger compression ratios at the cost of compression speed.
+Speed vs Compression trade-off is configurable by small increments.
+Decompression speed is preserved and remains roughly the same at all settings,
+a property shared by most LZ compression algorithms, such as [zlib] or lzma.
+
+The following tests were run
+on a server running Linux Debian (`Linux version 4.14.0-3-amd64`)
+with a Core i7-6700K CPU @ 4.0GHz,
+using [lzbench], an open-source in-memory benchmark by @inikep
+compiled with [gcc] 7.3.0,
+on the [Silesia compression corpus].
+
+Compression Speed vs Ratio | Decompression Speed
+---------------------------|--------------------
+![Compression Speed vs Ratio](doc/images/CSpeed2.png "Compression Speed vs Ratio") | ![Decompression Speed](doc/images/DSpeed3.png "Decompression Speed")
+
+A few other algorithms can produce higher compression ratios at slower speeds, falling outside of the graph.
+For a larger picture including slow modes, [click on this link](doc/images/DCspeed5.png).
+
+
+## The case for Small Data compression
+
+Previous charts provide results applicable to typical file and stream scenarios (several MB). Small data comes with different perspectives.
+
+The smaller the amount of data to compress, the more difficult it is to compress. This problem is common to all compression algorithms, and reason is, compression algorithms learn from past data how to compress future data. But at the beginning of a new data set, there is no "past" to build upon.
+
+To solve this situation, Zstd offers a __training mode__, which can be used to tune the algorithm for a selected type of data.
+Training Zstandard is achieved by providing it with a few samples (one file per sample). The result of this training is stored in a file called "dictionary", which must be loaded before compression and decompression.
+Using this dictionary, the compression ratio achievable on small data improves dramatically.
+
+The following example uses the `github-users` [sample set](https://github.com/facebook/zstd/releases/tag/v1.1.3), created from [github public API](https://developer.github.com/v3/users/#get-all-users).
+It consists of roughly 10K records weighing about 1KB each.
+
+Compression Ratio | Compression Speed | Decompression Speed
+------------------|-------------------|--------------------
+![Compression Ratio](doc/images/dict-cr.png "Compression Ratio") | ![Compression Speed](doc/images/dict-cs.png "Compression Speed") | ![Decompression Speed](doc/images/dict-ds.png "Decompression Speed")
+
+
+These compression gains are achieved while simultaneously providing _faster_ compression and decompression speeds.
+
+Training works if there is some correlation in a family of small data samples. The more data-specific a dictionary is, the more efficient it is (there is no _universal dictionary_).
+Hence, deploying one dictionary per type of data will provide the greatest benefits.
+Dictionary gains are mostly effective in the first few KB. Then, the compression algorithm will gradually use previously decoded content to better compress the rest of the file.
+
+### Dictionary compression How To:
+
+1. Create the dictionary
+
+   `zstd --train FullPathToTrainingSet/* -o dictionaryName`
+
+2. Compress with dictionary
+
+   `zstd -D dictionaryName FILE`
+
+3. Decompress with dictionary
+
+   `zstd -D dictionaryName --decompress FILE.zst`
+
+
+## Build instructions
+
+### Makefile
+
+If your system is compatible with standard `make` (or `gmake`),
+invoking `make` in root directory will generate `zstd` cli in root directory.
+
+Other available options include:
+- `make install` : create and install zstd cli, library and man pages
+- `make check` : create and run `zstd`, tests its behavior on local platform
+
+### cmake
+
+A `cmake` project generator is provided within `build/cmake`.
+It can generate Makefiles or other build scripts
+to create `zstd` binary, and `libzstd` dynamic and static libraries.
+
+By default, `CMAKE_BUILD_TYPE` is set to `Release`.
+
+### Meson
+
+A Meson project is provided within [`build/meson`](build/meson). Follow
+build instructions in that directory.
+
+You can also take a look at [`.travis.yml`](.travis.yml) file for an
+example about how Meson is used to build this project.
+
+Note that default build type is **release**.
+
+### Visual Studio (Windows)
+
+Going into `build` directory, you will find additional possibilities:
+- Projects for Visual Studio 2005, 2008 and 2010.
+  + VS2010 project is compatible with VS2012, VS2013, VS2015 and VS2017.
+- Automated build scripts for Visual compiler by [@KrzysFR](https://github.com/KrzysFR), in `build/VS_scripts`,
+  which will build `zstd` cli and `libzstd` library without any need to open Visual Studio solution.
+
+### Buck
+
+You can build the zstd binary via buck by executing: `buck build programs:zstd` from the root of the repo.
+The output binary will be in `buck-out/gen/programs/`.
+
+## Status
+
+Zstandard is currently deployed within Facebook. It is used continuously to compress large amounts of data in multiple formats and use cases.
+Zstandard is considered safe for production environments.

+Tutorial :
+----------
+The first step is to count all symbols. FSE_count() does this job very fast.
+Result will be saved into 'count', a table of unsigned int, which must be already allocated, and have 'maxSymbolValuePtr[0]+1' cells.
+'src' is a table of bytes of size 'srcSize'. All values within 'src' MUST be <= maxSymbolValuePtr[0]
+maxSymbolValuePtr[0] will be updated, with its real value (necessarily <= original value)
+FSE_count() will return the number of occurrence of the most frequent symbol.
+This can be used to know if there is a single symbol within 'src', and to quickly evaluate its compressibility.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).
+
+The next step is to normalize the frequencies.
+FSE_normalizeCount() will ensure that sum of frequencies is == 2 ^'tableLog'.
+It also guarantees a minimum of 1 to any Symbol with frequency >= 1.
+You can use 'tableLog'==0 to mean "use default tableLog value".
+If you are unsure of which tableLog value to use, you can ask FSE_optimalTableLog(),
+which will provide the optimal valid tableLog given sourceSize, maxSymbolValue, and a user-defined maximum (0 means "default").
+
+The result of FSE_normalizeCount() will be saved into a table,
+called 'normalizedCounter', which is a table of signed short.
+'normalizedCounter' must be already allocated, and have at least 'maxSymbolValue+1' cells.
+The return value is tableLog if everything proceeded as expected.
+It is 0 if there is a single symbol within distribution.
+If there is an error (ex: invalid tableLog value), the function will return an ErrorCode (which can be tested using FSE_isError()).
+
+'normalizedCounter' can be saved in a compact manner to a memory area using FSE_writeNCount().
+'buffer' must be already allocated.
+For guaranteed success, buffer size must be at least FSE_headerBound().
+The result of the function is the number of bytes written into 'buffer'.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError(); ex : buffer size too small).
+
+'normalizedCounter' can then be used to create the compression table 'CTable'.
+The space required by 'CTable' must be already allocated, using FSE_createCTable().
+You can then use FSE_buildCTable() to fill 'CTable'.
+If there is an error, both functions will return an ErrorCode (which can be tested using FSE_isError()).
+
+'CTable' can then be used to compress 'src', with FSE_compress_usingCTable().
+Similar to FSE_count(), the convention is that 'src' is assumed to be a table of char of size 'srcSize'
+The function returns the size of compressed data (without header), necessarily <= `dstCapacity`.
+If it returns '0', compressed data could not fit into 'dst'.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).

+BIT_DStream_endOfBuffer : Dstream reached end of buffer. Its container may no longer be completely filled.
+BIT_DStream_completed : Dstream reached its exact end, corresponding in general to decompression completed.
+BIT_DStream_tooFar : Dstream went too far. Decompression result is corrupted.
+
+When reaching end of buffer (BIT_DStream_endOfBuffer), progress slowly, notably if you decode multiple symbols per loop,
+to properly detect the exact end of stream.
+After each decoded symbol, check if DStream is fully consumed using this simple test :
+    BIT_reloadDStream(&DStream) >= BIT_DStream_completed
+
+When it's done, verify decompression is fully completed, by checking both DStream and the relevant states.
+Checking if DStream has reached its end is performed by :
+    BIT_endOfDStream(&DStream);
+Check also the states. There might be some symbols left there, if some high probability ones (>50%) are possible.

+For small input, prefer `XXH32()` and `XXH64()` .
+
+XXH state must first be allocated, using XXH*_createState() .
+
+Start a new hash by initializing state with a seed, using XXH*_reset().
+
+Then, feed the hash state by calling XXH*_update() as many times as necessary.
+Obviously, input must be allocated and read accessible.
+The function returns an error code, with 0 meaning OK, and any other value meaning there is an error.
+
+Finally, a hash value can be produced anytime, by using XXH*_digest().
+This function returns the nn-bits hash as an int or long long.
+
+It's still possible to continue inserting input into the hash state after a digest,
+and generate some new hashes later on, by calling again XXH*_digest().
+
+When done, free XXH state space if it was allocated dynamically.

+*  Streaming compression - howto

+*  A ZBUFF_CCtx object is required to track streaming operation.
+*  Use ZBUFF_createCCtx() and ZBUFF_freeCCtx() to create/release resources.
+*  ZBUFF_CCtx objects can be reused multiple times.
+*
+*  Start by initializing ZBUF_CCtx.
+*  Use ZBUFF_compressInit() to start a new compression operation.
+*  Use ZBUFF_compressInitDictionary() for a compression which requires a dictionary.
+*
+*  Use ZBUFF_compressContinue() repetitively to consume input stream.
+*  *srcSizePtr and *dstCapacityPtr can be any size.
+*  The function will report how many bytes were read or written within *srcSizePtr and *dstCapacityPtr.
+*  Note that it may not consume the entire input, in which case it's up to the caller to present again remaining data.
+*  The content of `dst` will be overwritten (up to *dstCapacityPtr) at each call, so save its content if it matters or change @dst .
+*  @return : a hint to preferred nb of bytes to use as input for next function call (it's just a hint, to improve latency)
+*            or an error code, which can be tested using ZBUFF_isError().
+*
+*  At any moment, it's possible to flush whatever data remains within buffer, using ZBUFF_compressFlush().
+*  The nb of bytes written into `dst` will be reported into *dstCapacityPtr.
+*  Note that the function cannot output more than *dstCapacityPtr,
+*  therefore, some content might still be left into internal buffer if *dstCapacityPtr is too small.
+*  @return : nb of bytes still present into internal buffer (0 if it's empty)
+*            or an error code, which can be tested using ZBUFF_isError().
+*
+*  ZBUFF_compressEnd() instructs to finish a frame.
+*  It will perform a flush and write frame epilogue.
+*  The epilogue is required for decoders to consider a frame completed.
+*  Similar to ZBUFF_compressFlush(), it may not be able to output the entire internal buffer content if *dstCapacityPtr is too small.
+*  In which case, call again ZBUFF_compressFlush() to complete the flush.
+*  @return : nb of bytes still present into internal buffer (0 if it's empty)
+*            or an error code, which can be tested using ZBUFF_isError().
+*
+*  Hint : _recommended buffer_ sizes (not compulsory) : ZBUFF_recommendedCInSize() / ZBUFF_recommendedCOutSize()
+*  input : ZBUFF_recommendedCInSize==128 KB block size is the internal unit, use this value to reduce intermediate stages (better latency)
+*  output : ZBUFF_recommendedCOutSize==ZSTD_compressBound(128 KB) + 3 + 3 : ensures it's always possible to write/flush/end a full block. Skip some buffering.
+*  By using both, it ensures that input will be entirely consumed, and output will always contain the result, reducing intermediate buffering.

+/*******************************************************************************
+  Introduction
+
+  zstd, short for Zstandard, is a fast lossless compression algorithm, targeting
+  real-time compression scenarios at zlib-level and better compression ratios.
+  The zstd compression library provides in-memory compression and decompression
+  functions.
+
+  The library supports regular compression levels from 1 up to ZSTD_maxCLevel(),
+  which is currently 22. Levels >= 20, labeled `--ultra`, should be used with
+  caution, as they require more memory. The library also offers negative
+  compression levels, which extend the range of speed vs. ratio preferences.
+  The lower the level, the faster the speed (at the cost of compression).
+
+  Compression can be done in:
+    - a single step (described as Simple API)
+    - a single step, reusing a context (described as Explicit context)
+    - unbounded multiple steps (described as Streaming compression)
+
+  The compression ratio achievable on small data can be highly improved using
+  a dictionary. Dictionary compression can be performed in:
+    - a single step (described as Simple dictionary API)
+    - a single step, reusing a dictionary (described as Bulk-processing
+      dictionary API)
+
+  Advanced experimental functions can be accessed using
+  `#define ZSTD_STATIC_LINKING_ONLY` before including zstd.h.
+
+  Advanced experimental APIs should never be used with a dynamically-linked
+  library. They are not "stable"; their definitions or signatures may change in
+  the future. Only static linking is allowed.

+*  Streaming compression - HowTo
+*
+*  A ZSTD_CStream object is required to track streaming operation.
+*  Use ZSTD_createCStream() and ZSTD_freeCStream() to create/release resources.
+*  ZSTD_CStream objects can be reused multiple times on consecutive compression operations.
+*  It is recommended to re-use ZSTD_CStream since it will play nicer with system's memory, by re-using already allocated memory.
+*
+*  For parallel execution, use one separate ZSTD_CStream per thread.
+*
+*  note : since v1.3.0, ZSTD_CStream and ZSTD_CCtx are the same thing.
+*
+*  Parameters are sticky : when starting a new compression on the same context,
+*  it will re-use the same sticky parameters as previous compression session.
+*  When in doubt, it's recommended to fully initialize the context before usage.
+*  Use ZSTD_initCStream() to set the parameter to a selected compression level.
+*  Use advanced API (ZSTD_CCtx_setParameter(), etc.) to set more specific parameters.
+*
+*  Use ZSTD_compressStream() as many times as necessary to consume input stream.
+*  The function will automatically update both `pos` fields within `input` and `output`.
+*  Note that the function may not consume the entire input,
+*  for example, because the output buffer is already full,
+*  in which case `input.pos < input.size`.
+*  The caller must check if input has been entirely consumed.
+*  If not, the caller must make some room to receive more compressed data,
+*  and then present again remaining input data.
+* @return : a size hint, preferred nb of bytes to use as input for next function call
+*           or an error code, which can be tested using ZSTD_isError().
+*           Note 1 : it's just a hint, to help latency a little, any value will work fine.
+*           Note 2 : size hint is guaranteed to be <= ZSTD_CStreamInSize()
+*
+*  At any moment, it's possible to flush whatever data might remain stuck within internal buffer,
+*  using ZSTD_flushStream(). `output->pos` will be updated.
+*  Note that, if `output->size` is too small, a single invocation of ZSTD_flushStream() might not be enough (return code > 0).
+*  In which case, make some room to receive more compressed data, and call again ZSTD_flushStream().
+*  @return : 0 if internal buffers are entirely flushed,
+*            >0 if some data still present within internal buffer (the value is minimal estimation of remaining size),
+*            or an error code, which can be tested using ZSTD_isError().
+*
+*  ZSTD_endStream() instructs to finish a frame.
+*  It will perform a flush and write frame epilogue.
+*  The epilogue is required for decoders to consider a frame completed.
+*  flush() operation is the same, and follows same rules as ZSTD_flushStream().
+*  @return : 0 if frame fully completed and fully flushed,
+*            >0 if some data still present within internal buffer (the value is minimal estimation of remaining size),
+*            or an error code, which can be tested using ZSTD_isError().

+*  Streaming decompression - HowTo
+*
+*  A ZSTD_DStream object is required to track streaming operations.
+*  Use ZSTD_createDStream() and ZSTD_freeDStream() to create/release resources.
+*  ZSTD_DStream objects can be re-used multiple times.
+*
+*  Use ZSTD_initDStream() to start a new decompression operation.
+* @return : recommended first input size
+*  Alternatively, use advanced API to set specific properties.
+*
+*  Use ZSTD_decompressStream() repetitively to consume your input.
+*  The function will update both `pos` fields.
+*  If `input.pos < input.size`, some input has not been consumed.
+*  It's up to the caller to present again remaining data.
+*  The function tries to flush all data decoded immediately, respecting output buffer size.
+*  If `output.pos < output.size`, decoder has flushed everything it could.
+*  But if `output.pos == output.size`, there might be some data left within internal buffers.,
+*  In which case, call ZSTD_decompressStream() again to flush whatever remains in the buffer.
+*  Note : with no additional input provided, amount of data flushed is necessarily <= ZSTD_BLOCKSIZE_MAX.
+* @return : 0 when a frame is completely decoded and fully flushed,
+*        or an error code, which can be tested using ZSTD_isError(),
+*        or any other value > 0, which means there is still some decoding or flushing to do to complete current frame :
+*                                the return value is a suggested next input size (just a hint for better latency)
+*                                that will never request more than the remaining frame size.

+     * - The CDict's tables can be used in-place. In this model, compression is

+     *   tables. However, this model incurs no start-up cost (as long as the
+     *   working context's tables can be reused). For small inputs, this can be
+     *   faster than copying the CDict's tables.
+     *
+     * Zstd has a simple internal heuristic that selects which strategy to use

+  Buffer-less streaming decompression (synchronous mode)
+
+  A ZSTD_DCtx object is required to track streaming operations.
+  Use ZSTD_createDCtx() / ZSTD_freeDCtx() to manage it.
+  A ZSTD_DCtx object can be re-used multiple times.
+
+  First typical operation is to retrieve frame parameters, using ZSTD_getFrameHeader().
+  Frame header is extracted from the beginning of compressed frame, so providing only the frame's beginning is enough.
+  Data fragment must be large enough to ensure successful decoding.
+ `ZSTD_frameHeaderSize_max` bytes is guaranteed to always be large enough.
+  @result : 0 : successful decoding, the `ZSTD_frameHeader` structure is correctly filled.
+           >0 : `srcSize` is too small, please provide at least @result bytes on next attempt.
+           errorCode, which can be tested using ZSTD_isError().
+
+  It fills a ZSTD_frameHeader structure with important information to correctly decode the frame,
+  such as the dictionary ID, content size, or maximum back-reference distance (`windowSize`).
+  Note that these values could be wrong, either because of data corruption, or because a 3rd party deliberately spoofs false information.
+  As a consequence, check that values remain within valid application range.
+  For example, do not allocate memory blindly, check that `windowSize` is within expectation.
+  Each application can set its own limits, depending on local restrictions.
+  For extended interoperability, it is recommended to support `windowSize` of at least 8 MB.
+
+  ZSTD_decompressContinue() needs previous data blocks during decompression, up to `windowSize` bytes.
+  ZSTD_decompressContinue() is very sensitive to contiguity,
+  if 2 blocks don't follow each other, make sure that either the compressor breaks contiguity at the same place,
+  or that previous contiguous segment is large enough to properly handle maximum back-reference distance.
+  There are multiple ways to guarantee this condition.
+
+  The most memory efficient way is to use a round buffer of sufficient size.
+  Sufficient size is determined by invoking ZSTD_decodingBufferSize_min(),
+  which can @return an error code if required value is too large for current system (in 32-bits mode).
+  In a round buffer methodology, ZSTD_decompressContinue() decompresses each block next to previous one,
+  up to the moment there is not enough room left in the buffer to guarantee decoding another full block,
+  which maximum size is provided in `ZSTD_frameHeader` structure, field `blockSizeMax`.
+  At which point, decoding can resume from the beginning of the buffer.
+  Note that already decoded data stored in the buffer should be flushed before being overwritten.
+
+  There are alternatives possible, for example using two or more buffers of size `windowSize` each, though they consume more memory.
+
+  Finally, if you control the compression process, you can also ignore all buffer size rules,
+  as long as the encoder and decoder progress in "lock-step",
+  aka use exactly the same buffer sizes, break contiguity at the same place, etc.
+
+  Once buffers are setup, start decompression, with ZSTD_decompressBegin().
+  If decompression requires a dictionary, use ZSTD_decompressBegin_usingDict() or ZSTD_decompressBegin_usingDDict().
+
+  Then use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue() alternatively.
+  ZSTD_nextSrcSizeToDecompress() tells how many bytes to provide as 'srcSize' to ZSTD_decompressContinue().
+  ZSTD_decompressContinue() requires this _exact_ amount of bytes, or it will fail.
+
+ @result of ZSTD_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity).
+  It can be zero : it just means ZSTD_decompressContinue() has decoded some metadata item.
+  It can also be an error code, which can be tested with ZSTD_isError().
+
+  A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero.
+  Context can then be reset to start a new decompression.
+
+  Note : it's possible to know if next input to present is a header or a block, using ZSTD_nextInputType().
+  This information is not required to properly decode a frame.
+
+  == Special case : skippable frames ==
+
+  Skippable frames allow integration of user-defined data into a flow of concatenated frames.
+  Skippable frames will be ignored (skipped) by decompressor.
+  The format of skippable frames is as follows :
+  a) Skippable frame ID - 4 Bytes, Little endian format, any value from 0x184D2A50 to 0x184D2A5F
+  b) Frame Size - 4 Bytes, Little endian format, unsigned 32-bits
+  c) Frame Content - any content (User Data) of length equal to Frame Size
+  For skippable frames ZSTD_getFrameHeader() returns zfhPtr->frameType==ZSTD_skippableFrame.
+  For skippable frames ZSTD_decompressContinue() always returns 0 : it only skips the content.

+    - Block size is limited, it must be <= ZSTD_getBlockSize() <= ZSTD_BLOCKSIZE_MAX == 128 KB
+      + If input is larger than a block size, it's necessary to split input data into multiple blocks
+      + For inputs larger than a single block, really consider using regular ZSTD_compress() instead.
