.SH Description
.NXR "yppasswd subroutine"
.NXAM "yppasswd subroutine" "yppasswdd daemon"
.NXR "password" "updating in YP map"
The 
.PN yppasswd
routine uses Remote Procedure Call (RPC) and External Data 
Representation (XDR) routines to update a user password in 
a Yellow Pages password map.  The RPC and XDR elements that are used are
listed below under the RPC INFO heading.
.PP
If
.I oldpass
is indeed the old user password,
this routine replaces the password entry with
.I newpw.
It returns 0 if successful.
