yppasswd(NS)

yppasswd -- update user password in Network Information Service (NIS)

Syntax

cc ... -lrpcsvc -lsocket

#include <rpcsvc/yppasswd.h>

yppasswd(oldpass, newpw)
char *oldpass;
struct passwd *newpw;

Description

If oldpass is indeed the old user password, this routine replaces the password entry with newpw.

NOTE: All routines in librpc and libyp have been incorporated into libsocket. libyp and libsocket have been retained so that existing Makefiles will continue to work. New code should be linked with libsocket.
