ProcPRC c contains all the source code needed for the example The file ProcPRC sIn in the same folder is a solution file for Visual C 7 1 There is also a compiled executable file available located in the folder SOURCE ProcPRC Release called ProcPRC exe It reads the packet recording file test prc and displays packet data in a console window 6 2 LPA Server and Clients Version 3 3 The LPA can forward information to third party applications while packets are logged This feature is activated by starting the LPA Server see Section 5 11 The LPA Server automatically writes all packets that pass through the capture filter see 5 3 into a packet ring buffer that can store up to 128 packets So called LPA Clients can access packet data on line by using the DLL LpaCli dll This DLL provides two functions to read packet data and wait for new packets To avoid blocking of the LPA software while packets are logged there is no hand shaking between the server and the clients This means that the clients must process packet data fast enough in order not to lose any packets Other than that there is no limitation on the number of clients running at the same time It is also possible to start and stop the LPA Clients as well as the LPA Server at any time the synchronization is always done automatically To create an LPA Client application the DLL Dynamic Link Library LpaCli dll which is located in the folder
