                                                                                     explain_tcgetattr_or_die(3)

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

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

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

       data    The data, exactly as to be passed to the tcgetattr(3) system call.

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

       explain_tcgetattr_or_die - get terminal parameters and report errors

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

       The  explain_tcgetattr_on_error  function  always  returns  the  value return by the wrapped tcgetattr(3)
       system call.
