|
|
* @include: 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. "std:*" will return all of the keys in the
|
|
* "std" 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>"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>"fs"</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
