explain_tcflush_or_die(3)  Library Functions Manual  explain_tcflush_or_die(3)

NAME
       explain_tcflush_or_die -	discard	terminal data and report errors

SYNOPSIS
       #include	<libexplain/tcflush.h>
       void explain_tcflush_or_die(int fildes, int selector);
       int explain_tcflush_on_error(int	fildes,	int selector);

DESCRIPTION
       The explain_tcflush_or_die function is used to call the tcflush(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from  the  explain_tcflush(3) function, and then	the process terminates
       by calling exit(EXIT_FAILURE).

       The explain_tcflush_on_error function is	used to	 call  the  tcflush(3)
       system  call.  On failure an explanation	will be	printed	to stderr, ob-
       tained from the explain_tcflush(3) function, but	still returns  to  the
       caller.

       fildes  The  fildes,  exactly  as to be passed to the tcflush(3)	system
	       call.

       selector
	       The selector, exactly as	to be passed to	the tcflush(3)	system
	       call.

RETURN VALUE
       The  explain_tcflush_or_die  function  only  returns  on	 success,  see
       tcflush(3) for more information.	On failure, prints an explanation  and
       exits, it does not return.

       The  explain_tcflush_on_error  function always returns the value	return
       by the wrapped tcflush(3) system	call.

EXAMPLE
       The explain_tcflush_or_die function is intended to be used in a fashion
       similar to the following	example:
	      explain_tcflush_or_die(fildes, selector);
