portmap_init_session()

static void portmap_init_session ( struct oncrpc_session *  session, struct oncrpc_cred *  credential  )

inlinestatic

Prepare an ONC RPC session to be used as a PORTMAP session.

Parameters

session	ONC RPC session
credential	ONC RPC credential

The credential parameter must not be NULL, use 'oncrpc_auth_none' if you don't want a particular scheme to be used.
