(setup): Remove FUNC_NAME and ALL arguments, assume they are always "setnetgrent" and 1. (endnetgrent_hook): New function. (internal_endnetgrent): Use it. (__internal_setnetgrent_reuse): Use it. Adjust setup caller. If status is NSS_STATUS_SUCCESS, yet action is continue, call endnetgrent hook. (internal_getnetgrent_r): Use __nss_lookup_function rather than setup. Recompute getfct pointer after successful __internal_setnetgrent_reuse. Don't use __nss_next. (innetgr): Use __nss_lookup_function instead of __nss_lookup. Adjust setup caller. * nss/nss_files/files-netgrp.c (_nss_files_endnetgrent): Always clear data_size and cursor. Add libnss_files_hidden_proto and libnss_files_hidden_def. (_nss_files_setnetgrent): Call _nss_files_endnetgrent on failure. * nis/nss_nis/nis-netgrp.c (internal_endnetgrent): Always clear data_size and cursor. (_nss_nis_setnetgrent): Don't call internal_endnetgrent. (_nss_nis_getnetgrent_r): Remove result->cursor == NULL handling. * nis/nss_nisplus/nisplus-netgrp.c (internal_endnetgrent): Always clear data_size and position. (_nss_nisplus_setnetgrent): Don't call internal_endnetgrent. 2005-09-09 Ulrich Drepper <drepper@redhat.com> * nss/getent.c (netgroup_keys): Call endnetgrent. (main): Call mtrace. * nss/nss_files/files-netgrp.c (_nss_files_setnetgrent): We don't need locking for the stream. Use feof_unlocked. 2005-09-09 Jakub Jelinek <jakub@redhat.com>
