explain_endgrent_or_die(3) Library Functions Manual explain_endgrent_or_die(3)

NAME
       explain_endgrent_or_die - finish	group file accesses and	report errors

SYNOPSIS
       #include	<libexplain/endgrent.h>
       void explain_endgrent_or_die(void);
       void explain_endgrent_on_error(void);

DESCRIPTION
       The  explain_endgrent_or_die  function  is used to call the endgrent(3)
       system call. On failure an explanation will be printed to  stderr,  ob-
       tained from the explain_endgrent(3) function, and then the process ter-
       minates by calling exit(EXIT_FAILURE).

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

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

       The  explain_endgrent_on_error function always returns the value	return
       by the wrapped endgrent(3) system call.

EXAMPLE
       The explain_endgrent_or_die function is intended	to be used in a	 fash-
       ion similar to the following example:
	      explain_endgrent_or_die();
