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