NAME
       explain_setlinebuf_or_die  - stream buffering operations	and report er-
       rors

SYNOPSIS
       #include	<libexplain/setlinebuf.h>
       void explain_setlinebuf_or_die(FILE *fp);
       void explain_setlinebuf_on_error(FILE *fp);

DESCRIPTION
       The  explain_setlinebuf_or_die  function	 is  used  to  call  the  set-
       linebuf(3)  system  call.  On failure an	explanation will be printed to
       stderr, obtained	from the explain_setlinebuf(3) function, and then  the
       process terminates by calling exit(EXIT_FAILURE).

       The  explain_setlinebuf_on_error	 function  is  used  to	 call the set-
       linebuf(3) system call. On failure an explanation will  be  printed  to
       stderr, obtained	from the explain_setlinebuf(3) function, but still re-
       turns to	the caller.

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

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

       The  explain_setlinebuf_on_error	 function always returns the value re-
       turn by the wrapped setlinebuf(3) system	call.

EXAMPLE
       The explain_setlinebuf_or_die function is intended  to  be  used	 in  a
       fashion similar to the following	example:
	      explain_setlinebuf_or_die(fp);
