No, this is not possible. There's seems to be no Unix interface to only use
selected name services per application. This is always system wide
controlled by /etc/nsswitch.conf (or equivalent files on some OS'es).

There's only one execption - through the resolver library it's possible to
directly use the DNS server, however this is not integrated with the
standars gethostbynname/addr functions call and requires extra programmatic
efforts to be used in an application.
