43 /**
44  * #GAppInfo and #GAppLaunchContext are used for describing and launching
45  * applications installed on the system.
46  * 
47  * As of GLib 2.20, URIs will always be converted to POSIX paths
48  * (using g_file_get_path()) when using g_app_info_launch() even if
49  * the application requested an URI and not a POSIX path. For example
50  * for an desktop-file based application with Exec key `totem
51  * %U` and a single URI, `sftp://foo/file.avi`, then
52  * `/home/user/.gvfs/sftp on foo/file.avi` will be passed. This will
53  * only work if a set of suitable GIO extensions (such as gvfs 2.26
54  * compiled with FUSE support), is available and operational; if this
55  * is not the case, the URI will be passed unmodified to the application.
56  * Some URIs, such as `mailto:`, of course cannot be mapped to a POSIX
57  * path (in gvfs there's no FUSE mount for it); such URIs will be
58  * passed unmodified to the application.
59  * 
60  * Specifically for gvfs 2.26 and later, the POSIX URI will be mapped
61  * back to the GIO URI in the #GFile constructors (since gvfs
62  * implements the #GVfs extension point). As such, if the application
63  * needs to examine the URI, it needs to use g_file_get_uri() or
64  * similar on #GFile. In other words, an application cannot assume
65  * that the URI passed to e.g. g_file_new_for_commandline_arg() is
66  * equal to the result of g_file_get_uri(). The following snippet
67  * illustrates this:
68  * 
69  * |[
70  * GFile *f;
71  * char *uri;
72  * 
73  * file = g_file_new_for_commandline_arg (uri_from_commandline);
74  * 
75  * uri = g_file_get_uri (file);
76  * strcmp (uri, uri_from_commandline) == 0;
77  * g_free (uri);
78  * 
79  * if (g_file_has_uri_scheme (file, "cdda"))
80  * {
81  * // do something special with uri
82  * }
83  * g_object_unref (file);
84  * ]|
85  * 
86  * This code will work when both `cdda://sr0/Track 1.wav` and
87  * `/home/user/.gvfs/cdda on sr0/Track 1.wav` is passed to the
88  * application. It should be noted that it's generally not safe
89  * for applications to rely on the format of a particular URIs.
90  * Different launcher applications (e.g. file managers) may have
91  * different ideas of what a given URI means.
