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();
