       The  explain_truncate_or_die  function  is  used  to  call  the  truncate(2)  system call.  On failure an
       explanation will be printed to stderr, obtained from explain_truncate(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_truncate_or_die(pathname, length);

       pathname
               The pathname, exactly as to be passed to the truncate(2) system call.

       length  The length, exactly as to be passed to the truncate(2) system call.

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