NAME

yppasswd − Update user password in Network Information Service (NIS) password map. 

SYNOPSIS

#include <rpcsvc/yppasswd.h>
int yppasswd(
        char ∗oldpass,
        struct passwd ∗newpw );

DESCRIPTION

The yppasswd() routine uses Remote Procedure Call (RPC) and External Data Representation (XDR) routines to update a user password in an Network Information Service (NIS) password map. The RPC and XDR elements that are used are listed below under the RPC INFO heading. 

If oldpass is indeed the old user password, this routine replaces the password entry with newpw. It returns 0 if successful.
