The .ATP Driver
The .ATP Driver Changes instituted for Phase 2
AppleTalk Phase 2 includes two changes to The .ATP Driver: you can now
cancel all calls to the ATPGetRequest function that are pending execution,
and you can now set the release timer for AppleTalk Transaction Protocol
(ATP) exactly-once (XO) service to one of five different values.
Canceling All Calls to the ATPGetRequest Function
The ATPGetRequest function sets a socket to receive a request sent by
another socket. If you call the ATPGetRequest function asynchronously, you
can have several calls to the function simultaneously pending execution. The
ATPKillAllGetReq function cancels all calls to the ATPGetRequest
function pending for a specific socket without closing the socket.
