ypupdate(3N) NETWORK FUNCTIONS ypupdate(3N)
NAME
ypupdate - changes yp information
SYNOPSIS
#include <rpcsvc/ypclnt.h>
ypupdate(domain, map, ypop, key, keylen, data, datalen)
char *domain;
char *map;
unsigned ypop
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 ypop 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
ypop 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 ypop as YPOPSTORE and no
error will be returned if the key already or does not exist.
To delete an entry, the value of ypop should be YPOPDELETE.
This routine depends upon secure RPC, and will not work
unless the network is running secure RPC.
