67 * @short_description: File and Directory Handling
69 * @see_also: #GFileInfo, #GFileEnumerator
71 * #GFile is a high level abstraction for manipulating files on a
72 * virtual file system. #GFiles are lightweight, immutable objects
73 * that do no I/O upon creation. It is necessary to understand that
74 * #GFile objects do not represent files, merely an identifier for a
75 * file. All file content I/O is implemented as streaming operations
76 * (see #GInputStream and #GOutputStream).
78 * To construct a #GFile, you can use:
79 * - g_file_new_for_path() if you have a path.
80 * - g_file_new_for_uri() if you have a URI.
81 * - g_file_new_for_commandline_arg() for a command line argument.
82 * - g_file_new_tmp() to create a temporary file from a template.
83 * - g_file_parse_name() from a UTF-8 string gotten from g_file_get_parse_name().
85 * One way to think of a #GFile is as an abstraction of a pathname. For
86 * normal files the system pathname is what is stored internally, but as
87 * #GFiles are extensible it could also be something else that corresponds
88 * to a pathname in a userspace implementation of a filesystem.
90 * #GFiles make up hierarchies of directories and files that correspond to
91 * the files on a filesystem. You can move through the file system with
92 * #GFile using g_file_get_parent() to get an identifier for the parent
93 * directory, g_file_get_child() to get a child within a directory,
94 * g_file_resolve_relative_path() to resolve a relative path between two
95 * #GFiles. There can be multiple hierarchies, so you may not end up at
96 * the same root if you repeatedly call g_file_get_parent() on two different
99 * All #GFiles have a basename (get with g_file_get_basename()). These names
100 * are byte strings that are used to identify the file on the filesystem
101 * (relative to its parent directory) and there is no guarantees that they
102 * have any particular charset encoding or even make any sense at all. If
103 * you want to use filenames in a user interface you should use the display
104 * name that you can get by requesting the
105 * %G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with g_file_query_info().
106 * This is guaranteed to be in UTF-8 and can be used in a user interface.
107 * But always store the real basename or the #GFile to use to actually
108 * access the file, because there is no way to go from a display name to
111 * Using #GFile as an identifier has the same weaknesses as using a path
112 * in that there may be multiple aliases for the same file. For instance,
113 * hard or soft links may cause two different #GFiles to refer to the same
114 * file. Other possible causes for aliases are: case insensitive filesystems,
115 * short and long names on FAT/NTFS, or bind mounts in Linux. If you want to
116 * check if two #GFiles point to the same file you can query for the
117 * %G_FILE_ATTRIBUTE_ID_FILE attribute. Note that #GFile does some trivial
118 * canonicalization of pathnames passed in, so that trivial differences in
119 * the path string used at creation (duplicated slashes, slash at end of
120 * path, "." or ".." path segments, etc) does not create different #GFiles.
122 * Many #GFile operations have both synchronous and asynchronous versions
123 * to suit your application. Asynchronous versions of synchronous functions
124 * simply have _async() appended to their function names. The asynchronous
125 * I/O functions call a #GAsyncReadyCallback which is then used to finalize
126 * the operation, producing a GAsyncResult which is then passed to the
127 * function's matching _finish() operation.
129 * It is highly recommended to use asynchronous calls when running within a
130 * shared main loop, such as in the main thread of an application. This avoids
131 * I/O operations blocking other sources on the main loop from being dispatched.
132 * Synchronous I/O operations should be performed from worker threads. See the
133 * [introduction to asynchronous programming section][async-programming] for
136 * Some #GFile operations almost always take a noticeable amount of time, and
137 * so do not have synchronous analogs. Notable cases include:
138 * - g_file_mount_mountable() to mount a mountable file.
139 * - g_file_unmount_mountable_with_operation() to unmount a mountable file.
140 * - g_file_eject_mountable_with_operation() to eject a mountable file.
142 * ## Entity Tags # {#gfile-etag}
144 * One notable feature of #GFiles are entity tags, or "etags" for
145 * short. Entity tags are somewhat like a more abstract version of the
146 * traditional mtime, and can be used to quickly determine if the file
147 * has been modified from the version on the file system. See the
149 * [specification](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html)
150 * for HTTP Etag headers, which are a very similar concept.
