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);
