71 * @short_description: File and Directory Handling
73 * @see_also: #GFileInfo, #GFileEnumerator
75 * #GFile is a high level abstraction for manipulating files on a
76 * virtual file system. #GFiles are lightweight, immutable objects
77 * that do no I/O upon creation. It is necessary to understand that
78 * #GFile objects do not represent files, merely an identifier for a
79 * file. All file content I/O is implemented as streaming operations
80 * (see #GInputStream and #GOutputStream).
82 * To construct a #GFile, you can use:
84 * <member>g_file_new_for_path() if you have a path.</member>
85 * <member>g_file_new_for_uri() if you have a URI.</member>
86 * <member>g_file_new_for_commandline_arg() for a command line argument.</member>
87 * <member>g_file_new_tmp() to create a temporary file from a template.</member>
88 * <member>g_file_parse_name() from a UTF-8 string gotten from g_file_get_parse_name().</member>
91 * One way to think of a #GFile is as an abstraction of a pathname. For
92 * normal files the system pathname is what is stored internally, but as
93 * #GFiles are extensible it could also be something else that corresponds
94 * to a pathname in a userspace implementation of a filesystem.
96 * #GFiles make up hierarchies of directories and files that correspond to
97 * the files on a filesystem. You can move through the file system with
98 * #GFile using g_file_get_parent() to get an identifier for the parent
99 * directory, g_file_get_child() to get a child within a directory,
100 * g_file_resolve_relative_path() to resolve a relative path between two
101 * #GFiles. There can be multiple hierarchies, so you may not end up at
102 * the same root if you repeatedly call g_file_get_parent() on two different
105 * All #GFiles have a basename (get with g_file_get_basename()). These names
106 * are byte strings that are used to identify the file on the filesystem
107 * (relative to its parent directory) and there is no guarantees that they
108 * have any particular charset encoding or even make any sense at all. If
109 * you want to use filenames in a user interface you should use the display
110 * name that you can get by requesting the
111 * %G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with g_file_query_info().
112 * This is guaranteed to be in UTF-8 and can be used in a user interface.
113 * But always store the real basename or the #GFile to use to actually
114 * access the file, because there is no way to go from a display name to
117 * Using #GFile as an identifier has the same weaknesses as using a path
118 * in that there may be multiple aliases for the same file. For instance,
119 * hard or soft links may cause two different #GFiles to refer to the same
120 * file. Other possible causes for aliases are: case insensitive filesystems,
121 * short and long names on FAT/NTFS, or bind mounts in Linux. If you want to
122 * check if two #GFiles point to the same file you can query for the
123 * %G_FILE_ATTRIBUTE_ID_FILE attribute. Note that #GFile does some trivial
124 * canonicalization of pathnames passed in, so that trivial differences in
125 * the path string used at creation (duplicated slashes, slash at end of
126 * path, "." or ".." path segments, etc) does not create different #GFiles.
128 * Many #GFile operations have both synchronous and asynchronous versions
129 * to suit your application. Asynchronous versions of synchronous functions
130 * simply have _async() appended to their function names. The asynchronous
131 * I/O functions call a #GAsyncReadyCallback which is then used to finalize
132 * the operation, producing a GAsyncResult which is then passed to the
133 * function's matching _finish() operation.
135 * Some #GFile operations do not have synchronous analogs, as they may
136 * take a very long time to finish, and blocking may leave an application
137 * unusable. Notable cases include:
139 * <member>g_file_mount_mountable() to mount a mountable file.</member>
140 * <member>g_file_unmount_mountable_with_operation() to unmount a mountable file.</member>
141 * <member>g_file_eject_mountable_with_operation() to eject a mountable file.</member>
144 * <para id="gfile-etag"><indexterm><primary>entity tag</primary></indexterm>
145 * One notable feature of #GFiles are entity tags, or "etags" for
146 * short. Entity tags are somewhat like a more abstract version of the
147 * traditional mtime, and can be used to quickly determine if the file has
148 * been modified from the version on the file system. See the HTTP 1.1
149 * <ulink url="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html">specification</ulink>
150 * for HTTP Etag headers, which are a very similar concept.
