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) system 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,  obtained  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);
