| * @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. |
| * |
| * Values are stored within the list in #GFileAttributeValue structures. |
| * Values can store different types, listed in the enum #GFileAttributeType. |
| * Upon creation of a #GFileAttributeValue, the type will be set to |
| * %G_FILE_ATTRIBUTE_TYPE_INVALID. |
| * |
| * The list of possible attributes for a filesystem (pointed to by a #GFile) is |
| * availible as a #GFileAttributeInfoList. This list is queryable by key names |
| * as indicated earlier. |
| * |
| * 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). |

| * <row><entry>Namspace</entry><entry>Description</entry></row> |
| * </thead> |
| * <tbody> |
| * <row><entry>"standard"</entry><entry>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.</entry></row> |
| * <row><entry>"etag"</entry><entry>The <link linkend="gfile-etag">"Entity Tag"</link> |
| * namespace. Currently, the only key in this namespace is "value", which contains |
| * the value of the current entity tag.</entry></row> |
| * <row><entry>"id"</entry><entry>The "Identification" namespace. This |
| * namespace is used by file managers and applications that list directories |
| * to check for loops and to uniquely identify files.</entry></row> |
| * <row><entry>"access"</entry><entry>The "Access" namespace. Used to check |
| * if a user has the proper privilidges 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.</entry></row> |
| * <row><entry>"mountable"</entry><entry>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.</entry></row> |
| * <row><entry>"time"</entry><entry>The "Time" namespace. Includes file |
| * access, changed, created times. </entry></row> |
| * <row><entry>"unix"</entry><entry>The "Unix" namespace. Includes UNIX-specific |
| * information and may not be available for all files. Examples include |
| * the UNIX "UID", "GID", etc.</entry></row> |
| * <row><entry>"dos"</entry><entry>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.</entry></row> |
| * <row><entry>"owner"</entry><entry>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.</entry></row> |
| * <row><entry>"thumbnail"</entry><entry>The "Thumbnail" namespace. Includes |
| * information about file thumbnails and their location within the file system. Exaples of |
| * keys in this namespace include "path" to get the location of a thumbnail, and "failed" |
| * to check if thumbnailing of the file failed.</entry></row> |
| * <row><entry>"filesystem"</entry><entry>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.</entry></row> |
| * <row><entry>"gvfs"</entry><entry>The "GVFS" namespace. Keys in this namespace |
| * contain information about the current GVFS backend in use. </entry></row> |
| * <row><entry>"xattr"</entry><entry>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.</entry></row> |
| * <row><entry>"xattr-sys"</entry><entry>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.</entry></row> |
| * <row><entry>"selinux"</entry><entry>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.</entry></row> |
| * </tbody> |
