Overview
The explain_fchownat_or_die function is used to call the fchownat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_fchownat(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_fchownat_on_error function is used to call the fchownat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_fchownat(3) function, but still returns to the caller.
