The explain_futimes_or_die function
is used to call the futimes(3) system
call. On failure an explanation will be
printed to stderr,
obtained from explain_futimes(3),
and then the process terminates
by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion
similar to the following example:
explain_futimes_or_die(fildes, tv);
fildes
The fildes, exactly as to be passed to the futimes(3) system call.
tv
The tv, exactly as to be passed to the futimes(3) system call.
Returns:
This function only returns on success.
On failure, prints an explanation and exits.
