NAME    [Toc]    [Back]

     yp_update - changes NIS information

SYNOPSIS    [Toc]    [Back]

     #include <rpcsvc/ypclnt.h>

     yp_update(char *domain, char *map,	unsigned ypop, char *key, int keylen,
	       char *data, int datalen);

DESCRIPTION    [Toc]    [Back]

     yp_update() is used to make changes to the	NIS database. The syntax is
     the same as that of yp_match() except for the extra parameter ypop	which
     may take on one of	four values. If	it is YPOP_CHANGE, then	the data
     associated	with the key will be changed to	the new	value. If the key is
     not found in the database,	then yp_update() will return YPERR_KEY.	 If
     ypop has the value	YPOP_INSERT, then the key-value	pair will be inserted
     into the database.	 The error YPERR_KEY is	returned if the	key already
     exists in the database.  To store an item into the	database without
     concern for whether it exists already or not, pass	ypop as	YPOP_STORE and
     no	error will be returned if the key already or does not exist.  To
     delete an entry, the value	of ypop	should be YPOP_DELETE.
