void explain_chown_or_die(const char *pathname, int owner, int group);
DESCRIPTION
The explain_chown_or_die function
is used to call the chown(2) system
call. On failure an explanation will be
printed to stderr,
obtained from explain_chown(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_chown_or_die(pathname, owner, group);
pathname
The pathname, exactly as to be passed to the chown(2) system call.
owner
The owner, exactly as to be passed to the chown(2) system call.
group
The group, exactly as to be passed to the chown(2) system call.
Returns:
This function only returns on success.
On failure, prints an explanation and exits.
