Explain CSMsgInterface() Function with Predefined Protocol
A REQUEST structure is created for each message sent to the server. Messages passed to CSMsgInterface() as *dataMSG will be copied into request.csData for transmission to the server. This entire process may be further optimized by using the REQUEST structure as the data interface in the client application rathert than a MSG structure.
REQUEST could then be passed to CSMsgInterface() instead of MSG, avoiding the unnecessary memory allocation and copy.
As we learned, predefined protocols are inherently not flexible. Our interface may be expanded, however to include more types of MSG protocols. Server components could then send and receive different application protocols based on differing requirements. The additional changes could be implemented as new parameters to CSMsginterface (), variable sizes passed in REQUEST, or could be manually coded via switch () statements for each client-server request.
