* inet/getnetgrent_r.c: Include assert. cvs/fedora-glibc-20050912T0656

	(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.
