Documentation

If you are writing a server you need to instantiate a CAVERNnet_parallelTcpServer_c object. Likewise if you are writing a client you need to instantiate a CAVERNnet_parallelTcpClient_c object.

Server setup: First, instantiate the CAVERNnet_parallelTcpServer_c class. Then call this object's init() method with the desired port number as parameter. After this, we call CAVERNnet_parallelTcpServer_c::checkForNewConnections(PortNumber). This is a blocking call that waits for the client to make a CAVERNnet_parallelTcpClient_c::connectToServer() call. checkForNewConnections() returns a pointer to a CAVERNnet_parallelTcpClient_c object, which you can use to communicate with the client. Note that you do not explicitly instantiate a CAVERNnet_parallelTcpClient_c object when you are using the server class. You can just declare a pointer to the client object and assign to this variable the return value of CAVERNnet_parallelTcpServer_c::checkForNewConnections function.

Client setup: We instantiate the CAVERNnet_parallelTcpClient_c class and call the CAVERNnet_parallelTcpClient_c::connectToServer(MachineName,PortNumber,NumberOfSockets) method. We then use this object to do a write and read.

int init(int port)
Open the server on a port. Typically after this call you sit in a loop and call checkForNewConnections to wait for incoming connections.
Returns:
FAILED if failed, OK if success

CAVERNnet_parallelTcpClient_c* checkForNewConnections()
Check to see if there is a request from clients for connection. If yes then return a CAVERNnet_parallelTcpClient_c object which you can then use to talk to the client.
