50 * @short_description: File and Directory Handling
52 * @see_also: #GFileInfo, #GFileEnumerator
54 * #GFile is a high level abstraction for manipulating files on a
55 * virtual file system. #GFile<!-- -->s are lightweight, immutable
56 * objects that do no I/O upon creation. It is necessary to understand that
57 * #GFile objects do not represent files, merely an identifier for a file. All
58 * file content I/O is implemented as streaming operations (see #GInputStream and
61 * To construct a #GFile, you can use:
62 * g_file_new_for_path() if you have a path.
63 * g_file_new_for_uri() if you have a URI.
64 * g_file_new_for_commandline_arg() for a command line argument.
65 * g_file_parse_name() from a utf8 string gotten from g_file_get_parse_name().
67 * One way to think of a #GFile is as an abstraction of a pathname. For normal
68 * files the system pathname is what is stored internally, but as #GFile<!-- -->s
69 * are extensible it could also be something else that corresponds to a pathname
70 * in a userspace implementation of a filesystem.
72 * #GFile<!-- -->s make up hierarchies of directories and files that correspond to the
73 * files on a filesystem. You can move through the file system with #GFile using
74 * g_file_get_parent() to get an identifier for the parent directory, g_file_get_child()
75 * to get a child within a directory, g_file_resolve_relative_path() to resolve a relative
76 * path between two #GFile<!-- -->s. There can be multiple hierarchies, so you may not
77 * end up at the same root if you repeatedly call g_file_get_parent() on two different
80 * All #GFile<!-- -->s have a basename (get with g_file_get_basename()). These names
81 * are byte strings that are used to identify the file on the filesystem (relative to
82 * its parent directory) and there is no guarantees that they have any particular charset
83 * encoding or even make any sense at all. If you want to use filenames in a user
84 * interface you should use the display name that you can get by requesting the
85 * %G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with g_file_query_info().
86 * This is guaranteed to be in utf8 and can be used in a user interface. But always
87 * store the real basename or the #GFile to use to actually access the file, because
88 * there is no way to go from a display name to the actual name.
90 * Using #GFile as an identifier has the same weaknesses as using a path in that
91 * there may be multiple aliases for the same file. For instance, hard or
92 * soft links may cause two different #GFile<!-- -->s to refer to the same file.
93 * Other possible causes for aliases are: case insensitive filesystems, short
94 * and long names on Fat/NTFS, or bind mounts in Linux. If you want to check if
95 * two #GFile<!-- -->s point to the same file you can query for the
96 * %G_FILE_ATTRIBUTE_ID_FILE attribute. Note that #GFile does some trivial
97 * canonicalization of pathnames passed in, so that trivial differences in the
98 * path string used at creation (duplicated slashes, slash at end of path, "."
99 * or ".." path segments, etc) does not create different #GFile<!-- -->s.
101 * Many #GFile operations have both synchronous and asynchronous versions
102 * to suit your application. Asynchronous versions of synchronous functions
103 * simply have _async() appended to their function names. The asynchronous
104 * I/O functions call a #GAsyncReadyCallback which is then used to finalize
105 * the operation, producing a GAsyncResult which is then passed to the
106 * function's matching _finish() operation.
108 * Some #GFile operations do not have synchronous analogs, as they may
109 * take a very long time to finish, and blocking may leave an application
110 * unusable. Notable cases include:
111 * g_file_mount_mountable() to mount a mountable file.
112 * g_file_unmount_mountable() to unmount a mountable file.
113 * g_file_eject_mountable() to eject a mountable file.
115 * <para id="gfile-etag"><indexterm><primary>entity tag</primary></indexterm>
116 * One notable feature of #GFile<!-- -->s are entity tags, or "etags" for
117 * short. Entity tags are somewhat like a more abstract version of the
118 * traditional mtime, and can be used to quickly determine if the file has
119 * been modified from the version on the file system. See the HTTP 1.1
120 * <ulink url="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html">specification</ulink>
121 * for HTTP Etag headers, which are a very similar concept.
