54  * #GFile is a high level abstraction for manipulating files on a
55  * virtual file system. #GFiles are lightweight, immutable objects
56  * 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
58  * file. All file content I/O is implemented as streaming operations
59  * (see #GInputStream and #GOutputStream).
60  * 
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_new_tmp() to create a temporary file from a template.
66  * - g_file_parse_name() from a UTF-8 string gotten from g_file_get_parse_name().
67  * 
68  * One way to think of a #GFile is as an abstraction of a pathname. For
69  * normal files the system pathname is what is stored internally, but as
70  * #GFiles are extensible it could also be something else that corresponds
71  * to a pathname in a userspace implementation of a filesystem.
72  * 
73  * #GFiles make up hierarchies of directories and files that correspond to
74  * the files on a filesystem. You can move through the file system with
75  * #GFile using g_file_get_parent() to get an identifier for the parent
76  * directory, g_file_get_child() to get a child within a directory,
77  * g_file_resolve_relative_path() to resolve a relative path between two
78  * #GFiles. There can be multiple hierarchies, so you may not end up at
79  * the same root if you repeatedly call g_file_get_parent() on two different
80  * files.
81  * 
82  * All #GFiles have a basename (get with g_file_get_basename()). These names
83  * are byte strings that are used to identify the file on the filesystem
84  * (relative to its parent directory) and there is no guarantees that they
85  * have any particular charset encoding or even make any sense at all. If
86  * you want to use filenames in a user interface you should use the display
87  * name that you can get by requesting the
88  * %G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with g_file_query_info().
89  * This is guaranteed to be in UTF-8 and can be used in a user interface.
90  * But always store the real basename or the #GFile to use to actually
91  * access the file, because there is no way to go from a display name to
92  * the actual name.
93  * 
94  * Using #GFile as an identifier has the same weaknesses as using a path
95  * in that there may be multiple aliases for the same file. For instance,
96  * hard or soft links may cause two different #GFiles to refer to the same
97  * file. Other possible causes for aliases are: case insensitive filesystems,
98  * short and long names on FAT/NTFS, or bind mounts in Linux. If you want to
99  * check if two #GFiles point to the same file you can query for the
100  * %G_FILE_ATTRIBUTE_ID_FILE attribute. Note that #GFile does some trivial
101  * canonicalization of pathnames passed in, so that trivial differences in
102  * the path string used at creation (duplicated slashes, slash at end of
103  * path, "." or ".." path segments, etc) does not create different #GFiles.
104  * 
105  * Many #GFile operations have both synchronous and asynchronous versions
106  * to suit your application. Asynchronous versions of synchronous functions
107  * simply have _async() appended to their function names. The asynchronous
108  * I/O functions call a #GAsyncReadyCallback which is then used to finalize
109  * the operation, producing a GAsyncResult which is then passed to the
110  * function's matching _finish() operation.
111  * 
112  * It is highly recommended to use asynchronous calls when running within a
113  * shared main loop, such as in the main thread of an application. This avoids
114  * I/O operations blocking other sources on the main loop from being dispatched.
115  * Synchronous I/O operations should be performed from worker threads. See the
116  * [introduction to asynchronous programming section][async-programming] for
117  * more.
118  * 
119  * Some #GFile operations almost always take a noticeable amount of time, and
120  * so do not have synchronous analogs. Notable cases include:
121  * - g_file_mount_mountable() to mount a mountable file.
122  * - g_file_unmount_mountable_with_operation() to unmount a mountable file.
123  * - g_file_eject_mountable_with_operation() to eject a mountable file.
124  * 
125  * ## Entity Tags # {#gfile-etag}
126  * 
127  * One notable feature of #GFiles are entity tags, or "etags" for
128  * short. Entity tags are somewhat like a more abstract version of the
129  * traditional mtime, and can be used to quickly determine if the file
130  * has been modified from the version on the file system. See the
131  * HTTP 1.1
132  * [specification](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html)
133  * for HTTP Etag headers, which are a very similar concept.
