                                                                                     explain_setbuffer_or_die(3)

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

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

       fp      The fp, exactly as to be passed to the setbuffer(3) system call.

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

       size    The size, exactly as to be passed to the setbuffer(3) system call.

       The explain_setbuffer_or_die function is intended to be used  in  a  fashion  similar  to  the  following
       example:
              void result = explain_setbuffer_or_die(fp, data, size);

       explain_setbuffer_or_die - stream buffering operations and report errors

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

       The  explain_setbuffer_on_error  function  always  returns  the  value return by the wrapped setbuffer(3)
       system call.
