4 Conversation States
Conversation states indicate the status of each side of a conversation.
Application programmers on different processors use conversation
states to discuss how their TPs will communicate. Certain intrinsics (or
verbs, depending on the implementation) can be called from each state,
and control information is exchanged through parameters of the
intrinsics. Control information sent by the remote TP may determine
the state of the local side of the conversation.
This chapter defines all the possible states of a conversation and
explains how the various intrinsics affect these states. The possible
states of a conversation are listed in Table 4-1.
