On failure an explanation will be printed to stderr, obtained from the explain_getdomainname(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_getdomainname_on_error function is used to call the getdo- mainname(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_getdomainname(3) function, but still returns to the caller. data The data, exactly as to be passed to the getdomainname(2) sys- tem call. data_size The data_size, exactly as to be passed to the getdomainname(2) system call. RETURN VALUE The explain_getdomainname_or_die function only returns on success, see getdomainname(2) for more information. On failure, prints an explana- tion and exits, it does not return. The explain_getdomainname_on_error function always returns the value return by the wrapped getdomainname(2) system call.
