NAME

       explain_setlinebuf_or_die - stream buffering operations and report errors

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 setlinebuf(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 setlinebuf(3) system call. On  failure  an	explanation  will  be  printed	to
       stderr, obtained from the explain_setlinebuf(3) function, but still returns 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 return 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);
