void explain_fchown_or_die(int fildes, int owner, int group);
DESCRIPTION
The explain_fchown_or_die function
is used to call the fchown(2) system
call. On failure an explanation will be
printed to stderr,
obtained from explain_fchown(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_fchown_or_die(fildes, owner, group);
fildes
The fildes, exactly as to be passed to the fchown(2) system call.
owner
The owner, exactly as to be passed to the fchown(2) system call.
group
The group, exactly as to be passed to the fchown(2) system call.
Returns:
This function only returns on success.
On failure, prints an explanation and exits.
