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, obtained from  the  explain_endgrent(3)  function,  and  then  the
       process terminates 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, obtained 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 endgrent(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 fashion similar to the following
       example:
              explain_endgrent_or_die();
