NAME

SYNOPSIS

     as a repository of invitations, responding to requests by clients wishing to rendezvous to hold a con-versation. conversation.
     versation.  In normal operation, a client, the caller, initiates a rendezvous by sending a CTL_MSG to
     the server of type LOOK_UP (see <protocols/talkd.h>).  This causes the server to search its invitation
     tables to check if an invitation currently exists for the caller (to speak to the callee specified in
     the message).  If the lookup fails, the caller then sends an ANNOUNCE message causing the server to
     broadcast an announcement on the callee's login ports requesting contact.  When the callee responds,
     the local server uses the recorded invitation to respond with the appropriate rendezvous address and
     the caller and callee client programs establish a stream connection through which the conversation
     takes place.
