yppasswd - update user password in NIS
The yppasswd() protocol is used to change a user's password entry in
the Network Information Service (NIS) password database.
If oldpass is indeed the old user password, this routine replaces the
password entry with newpw. It returns 0 if successful.
struct passwd *newpw;
The Network Information Service (NIS) was formerly known as Sun Yellow
Pages (YP). The functionality of the two remains the same; only the
name has changed. The name Yellow Pages is a registered trademark in
