 * Purpose:     Gets the name of the file to which object OBJ_ID belongs.
 *              If 'name' is non-NULL then write up to 'size' bytes into that
 *              buffer and always return the length of the entry name.
 *              Otherwise `size' is ignored and the function does not store
 *              the name, just returning the number of characters required to
 *              store the name. If an error occurs then the buffer pointed to
 *              by 'name' (NULL or non-NULL) is unchanged and the function
 *              returns a negative value.
 *
 * Note:        This routine returns the name that was used to open the file,
 *              not the actual name after resolving symlinks, etc.
 *
 * Return:      Success:    The length of the file name
