DESCRIPTION

     The talkd utility is the server that notifies a user that someone else
     wants to initiate a conversation.  It acts as a repository of invita-
     tions, responding to requests by clients wishing to rendezvous to hold a
     conversation.  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.
