DESCRIPTION

       The explain_tcdrain_or_die function is used to call the tcdrain(3) system call. On failure

       and then the process terminates by calling exit(EXIT_FAILURE).

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