| * @short_description: Key-Value Paired File Attributes |
| * @include: gio/gio.h |
| * @see_also: #GFile, #GFileInfo |
| * |
| * File attributes in GIO consist of a list of key-value pairs. |
| * |
| * Keys are strings that contain a key namespace and a key name, separated |
| * by a colon, e.g. "namespace::keyname". Namespaces are included to sort |
| * key-value pairs by namespaces for relevance. Keys can be retrived |
| * using wildcards, e.g. "standard::*" will return all of the keys in the |
| * "standard" namespace. |
| * |
| * The list of possible attributes for a filesystem (pointed to by a #GFile) is |
| * available as a #GFileAttributeInfoList. This list is queryable by key names |
| * as indicated earlier. |
| * |
| * Information is stored within the list in #GFileAttributeInfo structures. |
| * The info structure can store different types, listed in the enum |
| * #GFileAttributeType. Upon creation of a #GFileAttributeInfo, the type will |
| * be set to %G_FILE_ATTRIBUTE_TYPE_INVALID. |
| * |
| * Classes that implement #GFileIface will create a #GFileAttributeInfoList and |
| * install default keys and values for their given file system, architecture, |
| * and other possible implementation details (e.g., on a UNIX system, a file |
| * attribute key will be registered for the user id for a given file). |
| * |
| * ## Default Namespaces |
| * |
| * - `"standard"`: The "Standard" namespace. General file information that |
| * any application may need should be put in this namespace. Examples |
| * include the file's name, type, and size. |
| * - `"etag`: The [Entity Tag][gfile-etag] namespace. Currently, the only key |
| * in this namespace is "value", which contains the value of the current |
| * entity tag. |
| * - `"id"`: The "Identification" namespace. This namespace is used by file |
| * managers and applications that list directories to check for loops and |
| * to uniquely identify files. |
| * - `"access"`: The "Access" namespace. Used to check if a user has the |
| * proper privileges to access files and perform file operations. Keys in |
| * this namespace are made to be generic and easily understood, e.g. the |
| * "can_read" key is %TRUE if the current user has permission to read the |
| * file. UNIX permissions and NTFS ACLs in Windows should be mapped to |
| * these values. |
| * - `"mountable"`: The "Mountable" namespace. Includes simple boolean keys |
| * for checking if a file or path supports mount operations, e.g. mount, |
| * unmount, eject. These are used for files of type %G_FILE_TYPE_MOUNTABLE. |
| * - `"time"`: The "Time" namespace. Includes file access, changed, created |
| * times. |
| * - `"unix"`: The "Unix" namespace. Includes UNIX-specific information and |
| * may not be available for all files. Examples include the UNIX "UID", |
| * "GID", etc. |
| * - `"dos"`: The "DOS" namespace. Includes DOS-specific information and may |
| * not be available for all files. Examples include "is_system" for checking |
| * if a file is marked as a system file, and "is_archive" for checking if a |
| * file is marked as an archive file. |
| * - `"owner"`: The "Owner" namespace. Includes information about who owns a |
| * file. May not be available for all file systems. Examples include "user" |
| * for getting the user name of the file owner. This information is often |
| * mapped from some backend specific data such as a UNIX UID. |
| * - `"thumbnail"`: The "Thumbnail" namespace. Includes information about file |
| * thumbnails and their location within the file system. Examples of keys in |
| * this namespace include "path" to get the location of a thumbnail, "failed" |
| * to check if thumbnailing of the file failed, and "is-valid" to check if |
| * the thumbnail is outdated. |
| * - `"filesystem"`: The "Filesystem" namespace. Gets information about the |
| * file system where a file is located, such as its type, how much space is |
| * left available, and the overall size of the file system. |
| * - `"gvfs"`: The "GVFS" namespace. Keys in this namespace contain information |
| * about the current GVFS backend in use. |
| * - `"xattr"`: The "xattr" namespace. Gets information about extended |
| * user attributes. See attr(5). The "user." prefix of the extended user |
| * attribute name is stripped away when constructing keys in this namespace, |
| * e.g. "xattr::mime_type" for the extended attribute with the name |
| * "user.mime_type". Note that this information is only available if |
| * GLib has been built with extended attribute support. |
| * - `"xattr-sys"`: The "xattr-sys" namespace. Gets information about |
| * extended attributes which are not user-specific. See attr(5). Note |
| * that this information is only available if GLib has been built with |
| * extended attribute support. |
| * - `"selinux"`: The "SELinux" namespace. Includes information about the |
| * SELinux context of files. Note that this information is only available |
| * if GLib has been built with SELinux support. |
| * |
| * Please note that these are not all of the possible namespaces. |
| * More namespaces can be added from GIO modules or by individual applications. |
| * For more information about writing GIO modules, see #GIOModule. |
| * |
| * <!-- TODO: Implementation note about using extended attributes on supported |
| * file systems --> |
| * |
| * ## Default Keys |
| * |
| * For a list of the built-in keys and their types, see the |
| * [GFileInfo][GFileInfo] documentation. |
| * |
| * Note that there are no predefined keys in the "xattr" and "xattr-sys" |
| * namespaces. Keys for the "xattr" namespace are constructed by stripping |
| * away the "user." prefix from the extended user attribute, and prepending |
| * "xattr::". Keys for the "xattr-sys" namespace are constructed by |
| * concatenating "xattr-sys::" with the extended attribute name. All extended |
| * attribute values are returned as hex-encoded strings in which bytes outside |
| * the ASCII range are encoded as escape sequences of the form \x`nn` |
| * where `nn` is a 2-digit hexadecimal number. |
