On failure an explanation will be printed to stderr, ob- tained from the explain_futimens(3) function, and then the process ter- minates by calling exit(EXIT_FAILURE). The explain_futimens_on_error function is used to call the futimens(3) system call. On failure an explanation will be printed to stderr, ob- tained from the explain_futimens(3) function, but still returns to the caller. fildes The fildes, exactly as to be passed to the futimens(3) system call. data The data, exactly as to be passed to the futimens(3) system call. RETURN VALUE The explain_futimens_or_die function only returns on success, see futi- mens(3) for more information. On failure, prints an explanation and ex- its, it does not return. The explain_futimens_on_error function always returns the value return by the wrapped futimens(3) system call.
