A Client Server Diagram: Sending Commands and Responses

The diagram given below shows a simple example of a Client - Server connection and a series of function calls used to send commands and responses.

Client	Action	Server
L_InetStartUp	Initialize the LEADTOOLS Peer-to-Peer DLL.	L_InetStartUp
	Set the computer to act as a server and listen for connection requests	L_InetServerInit
L_InetConnect	--------------------------------------------------> The client requests a connection with the server. This generates a call to the L_InetAcceptConnect on the server.
L_InetConnect	<-------------------------------------------------- The server accepts the connection request. This generates a call to the L_InetConnect function on the client.	L_InetAcceptConnect
	The server must override the L_InetSetCommandCallback function so it will be notified of commands received from the client. The client must override the L_InetSetResponseCallback function so it will be notified of responses received from the server.
L_InetSendLoadCmd	--------------------------------------------------> The client sends a load command to the server to load a specific image. This generates a call to the L_InetSetCommandCallback on the server.	L_InetSetCommandCallback
L_InetSetResponseCallback	<-------------------------------------------------- The server receives the load command and responds by calling L_InetSendLoadRsp. This generates a call to the L_InetSetResponseCallback function on the client.	L_InetSendLoadRsp
L_InetSendCmd	--------------------------------------------------> The client sends a flip command using the L_InetSendCmd function. This generates another call to the L_InetSetCommandCallback function on the server.	L_InetSetCommandCallback
L_InetSetResponseCallback	<-------------------------------------------------- The server calls LInet::SendRsp in response to receiving the L_InetSendCmd call from the client. This generates another call to the L_InetSetResponseCallback function on the client.	L_InetSendRsp
L_InetSendSaveCmd	--------------------------------------------------> The client sends a save command using the L_InetSendSaveCmd function. This generates another call to the L_InetSetCommandCallback function on the server.	L_InetSetCommandCallback
L_InetSetResponseCallback	<-------------------------------------------------- The server calls L_InetSendSaveRsp in response to receiving the L_InetSendSaveCmd call from the client. This generates another call to the L_InetSetResponseCallback function on the client.	L_InetSendSaveRsp
L_InetClose	The client has finished sending all the commands and closes the connection to the server.
