SYNOPSIS

9       #include <libexplain/endgrent.h>
10       void explain_endgrent_or_die(void);

DESCRIPTION

14       The  explain_endgrent_or_die  function  is used to call the endgrent(3)
15       system call. On failure an  explanation  will  be  printed  to  stderr,
16       obtained  from  the  explain_endgrent(3) function, and then the process
17       terminates by calling exit(EXIT_FAILURE).
18
19       The explain_endgrent_on_error function is used to call the  endgrent(3)
20       system  call.  On  failure  an  explanation  will be printed to stderr,
21       obtained from the explain_endgrent(3) function, but  still  returns  to
22       the caller.
23

RETURN VALUE

25       The  explain_endgrent_or_die function only returns on success, see end‐
26       grent(3) for more information. On failure, prints  an  explanation  and
27       exits, it does not return.
28
29       The  explain_endgrent_on_error function always returns the value return
30       by the wrapped endgrent(3) system call.
