                                                                                        explain_tcflow_or_die(3)

       The  explain_tcflow_or_die  function is used to call the tcflow(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_tcflow(3) function, and then the process  terminates
       by calling exit(EXIT_FAILURE).

       The explain_tcflow_on_error function is used to call the tcflow(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_tcflow(3) function, but still returns to the caller.

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

       action  The action, exactly as to be passed to the tcflow(3) system call.

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

       explain_tcflow_or_die - terminal flow control and report errors

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

       The explain_tcflow_on_error function always returns the value return  by  the  wrapped  tcflow(3)  system
       call.
