gnome_vfs_uri_get_fragment_identifier ()

const gchar* gnome_vfs_uri_get_fragment_identifier

gnome_vfs_uri_extract_dirname ()

gchar*      gnome_vfs_uri_extract_dirname   (const GnomeVFSURI *uri);

                                            (const GnomeVFSURI *uri);

Retrieve base file name for uri, ignoring any trailing path separators. This matches the XPG definition of basename, but not g_basename. This is often useful when you want the name of something that's pointed to by a uri, and don't care whether the uri has a directory or file form. If uri points to the root of a domain, returns the host name. If there's no host name, returns GNOME_VFS_URI_PATH_STR.

See also: gnome_vfs_uri_extract_short_path_name.

uri : A GnomeVFSURI
Returns : A pointer to the newly allocated string representing the unescaped short form of the name.

                                            (const GnomeVFSURI *uri);

Retrieve base file name for uri, ignoring any trailing path separators. This matches the XPG definition of basename, but not g_basename. This is often useful when you want the name of something that's pointed to by a uri, and don't care whether the uri has a directory or file form. If uri points to the root (including the root of any domain), returns GNOME_VFS_URI_PATH_STR.

See also: gnome_vfs_uri_extract_short_name.

uri : A GnomeVFSURI
Returns : A pointer to the newly allocated string representing the escaped short form of the name.

gnome_vfs_uri_hequal ()

gint        gnome_vfs_uri_hequal            (gconstpointer a,
                                             gconstpointer b);

a : a pointer to a GnomeVFSURI
b : a pointer to a GnomeVFSURI
Returns : TRUE if the URIs are the same

gnome_vfs_uri_hash ()

guint       gnome_vfs_uri_hash              (gconstpointer p);

Creates an integer value from a GnomeVFSURI, appropriate for using as the key to a hash table entry.

p : a pointer to a GnomeVFSURI
Returns : a hash key corresponding to p

gnome_vfs_uri_list_parse ()

GList*      gnome_vfs_uri_list_parse        (const gchar *uri_list);

gnome_vfs_uri_list_unref ()

GList*      gnome_vfs_uri_list_unref        (GList *list);

list : list of GnomeVFSURI elements
Returns : list

gnome_vfs_uri_list_copy ()

GList*      gnome_vfs_uri_list_copy         (GList *list);

list : list of GnomeVFSURI elements
Returns : a newly referenced duplicate of list

gnome_vfs_uri_list_free ()

void        gnome_vfs_uri_list_free         (GList *list);
