NAME
H5G_user_path_test
PURPOSE
Retrieve the user path for an ID
USAGE
herr_t H5G_user_path_test(obj_id, user_path, user_path_len)
hid_t obj_id; IN: ID to check
char *user_path; OUT: Pointer to buffer for User path
size_t *user_path_len; OUT: Size of user path
unsigned *obj_hidden; OUT: Whether object is hidden
RETURNS
Non-negative on success, negative on failure
DESCRIPTION
Retrieves the user path for an ID. A zero for the length is returned in
the case of no user path.
