On failure an explanation will be printed to stderr, obtained from the ex- plain_mknod(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_mknod_on_error function is used to call the mknod(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_mknod(3) function, but still returns to the caller. pathname The pathname, exactly as to be passed to the mknod(2) system call. mode The mode, exactly as to be passed to the mknod(2) system call. dev The dev, exactly as to be passed to the mknod(2) system call. RETURN VALUE The explain_mknod_or_die function only returns on success, see mknod(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_mknod_on_error function always returns the value return by the wrapped mknod(2) system call.
