NAME
yp_update - changes yp information
SYNOPSIS
#include <rpcsvc/ypclnt.h>
ypupdate(domain, map, op, key, keylen, data, datalen)
char *domain;
char *map;
unsigned op;
char *key;
int keylen;
char *data;
int datalen;
DESCRIPTION
ypupdate() is used to make changes to the YP database. The syntax
is the same as that of ypmatch() except for the extra parameter op
which may take on one of four values. If it is YPOPCHANGE then the
data associated with the key will be changed to the new value. If
the key is not found in the database, then ypupdate() will return
YPERRKEY. If op has the value YPOPINSERT then the key-value pair
will be inserted into the database. The error YPERRKEY 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
op as YPOPSTORE and no error will be returned if the key already or
does not exist. To delete an entry, the value of op should be
YPOPDELETE.
This routine depends upon secure RPC, and will not work unless the
network is running secure RPC.
