Purpose

The GetMessageSize API function returns the size of the current message buffer. This includes the NonStop RSC/MP header, Gen data, and user data.

If the second parameter passed into the main entry point, RSCUserEntry(), is 1 then this signifies that the exit is being called just prior sending the request message to the target server. The message size returned will be that of the message about to be sent to the server.

If the second parameter passed into the main entry point, RSCUserEntry(), is 0 then this signifies that the exit is being called just after the response message has been received from the target server. The message size returned is that of the message just received from the server.
