On failure an explanation will be printed to stderr, obtained from the explain_setlinebuf(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_setlinebuf_on_error function is used to call the setlinebuf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_setlinebuf(3) function, but still returns to the caller. fp The fp, exactly as to be passed to the setlinebuf(3) system call. RETURN VALUE The explain_setlinebuf_or_die function only returns on success, see setlinebuf(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_setlinebuf_on_error function always returns the value return by the wrapped setlinebuf(3) system call.
