Port Objects<br />

ALPC exports port objects to maintain state of communication:<br />

Server connection port: named port, server connection request<br />

point<br />

Server communication port: unnamed port, one per active client,<br />

used for communication<br />

Client communication port: unnamed port a particular client<br />

thread uses to communicate with a particular server<br />

Typical scenario:<br />

Server creates named connection port<br />

Client makes connection request<br />

Two unnamed ports are created, client gets handle to server port,<br />

server gets handle to client port<br />

These two new ports will be used for communication
