On failure an explanation will be printed to stderr, ob- tained from the explain_setgrent(3) function, and then the process ter- minates by calling exit(EXIT_FAILURE). The explain_setgrent_on_error function is used to call the setgrent(3) system call. On failure an explanation will be printed to stderr, ob- tained from the explain_setgrent(3) function, but still returns to the caller. RETURN VALUE The explain_setgrent_or_die function only returns on success, see set- grent(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_setgrent_on_error function always returns the value return by the wrapped setgrent(3) system call.
