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

       This function is intended to be used in a fashion similar to the following example:
              explain_putchar_or_die(c);

       c       The c, exactly as to be passed to the putchar(3) system call.

       Returns:
               This function only returns on success.  On failure, prints an explanation and exits.
