websocket example with server initiated data

[harsh P]

Hi, 

I am struggling with basic example to run webSocket with libonion. I am 2 days old with the web programming.  

My ultimate goal is to achieve the following 

1. start a websocket server on C++
2. Listen for messages from client
3. Send response for messages based on some processing in my custom code.
4. SEND SERVER INITIATED text message/string to client when something changes on my custom code.
   How do I achieve the above ? Any example code?

Below I am trying to provide more information by dummy test class below.
test.cpp
class test
{
public:
void processDataFromClient(const string & data);//this needs to get filled by websocket read method? how?
void pushDataToClient(const string & data);

};
test::pushDataToClient(const string & data)
{
(socketId, text) // how do I call this from my test.cpp ?
}

test::void processDataFromClient(const string & data)
{
//do some computation based on the text received
//turn on the light
//once Light is on for a minute call
pushDataToClient( lighton) ;
}

//websocket_server.cpp
main
{
//open a webSocket
//listen for messages from client i.e pass data received from onion_websocket_read to test class by calling processDataFromClient();
//send asynchronous messages to client received from test class. i.e. pushDataToClient should invoke onion_websocket_write //do we need a thread for this ? how to achieve this?

}
