explain_setvbuf_or_die(3)  Library Functions Manual  explain_setvbuf_or_die(3)

NAME
       explain_setvbuf_or_die -	stream buffering operations and	report errors

SYNOPSIS
       #include	<libexplain/setvbuf.h>
       void  explain_setvbuf_or_die(FILE  *fp,	char  *data,  int mode,	size_t
       size);
       int explain_setvbuf_on_error(FILE *fp, char  *data,  int	 mode,	size_t
       size);

DESCRIPTION
       The explain_setvbuf_or_die function is used to call the setvbuf(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from  the  explain_setvbuf(3) function, and then	the process terminates
       by calling exit(EXIT_FAILURE).

       The explain_setvbuf_on_error function is	used to	 call  the  setvbuf(3)
       system  call.  On failure an explanation	will be	printed	to stderr, ob-
       tained from the explain_setvbuf(3) function, but	still returns  to  the
       caller.

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

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

       mode    The mode, exactly as to be  passed  to  the  setvbuf(3)	system
	       call.

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

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

       The explain_setvbuf_on_error function always returns the	 value	return
       by the wrapped setvbuf(3) system	call.

EXAMPLE
       The explain_setvbuf_or_die function is intended to be used in a fashion
       similar to the following	example:
	      explain_setvbuf_or_die(fp, data, mode, size);
