                                                                                     explain_ftruncate_or_die(3)

       The  explain_ftruncate_or_die  function  is  used  to  call  the ftruncate(2) system call.  On failure an
       explanation will be  printed  to  stderr,  obtained  from  explain_ftruncate(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_ftruncate_or_die(fildes, length);

       fildes  The fildes, exactly as to be passed to the ftruncate(2) system call.

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

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