VfsFileLookupFunc

This function type is used by g_vfs_register_uri_scheme() to make it possible for a client to associate a URI scheme to a different #GFile implementation.

The client should return a reference to the new file that has been created for @uri, or null to continue with the default implementation.

• param identifier the identifier to look up a #GFile for. This can either be a URI or a parse name as returned by g_file_get_parse_name()

• return a #GFile for @identifier.
