explain_setbuf_or_die(3)   Library Functions Manual   explain_setbuf_or_die(3)

NAME
       explain_setbuf_or_die - set stream buffer and report errors

SYNOPSIS
       #include	<libexplain/setbuf.h>
       void explain_setbuf_or_die(FILE *fp, char *data);
       void explain_setbuf_on_error(FILE *fp, char *data);

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

       The explain_setbuf_on_error function is used to call the	setbuf(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_setbuf(3) function, but	still returns to the caller.

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

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

RETURN VALUE
       The explain_setbuf_or_die function only returns on  success,  see  set-
       buf(3)  for more	information. On	failure, prints	an explanation and ex-
       its, it does not	return.

       The explain_setbuf_on_error function always returns the value return by
       the wrapped setbuf(3) system call.

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