lws minimal ws client tx

This demonstrates a ws "publisher" to go with the minimal-ws-broker example.

Two threads are spawned that produce messages to be sent to the broker, via a local ringbuffer. Locking is provided to make ringbuffer access threadsafe.

When a nailed-up client connection to the broker is established, the ringbuffer is sent to the broker, which distributes the events to all connected clients.

build

 $ cmake . && make

usage

This example connects to ws-server/minimal-ws-broker, so you need to build and run that in another terminal.

 $ ./lws-minimal-ws-client-tx

[2018/03/16 16:04:33:5774] USER:   Run minimal-ws-broker and browse to that

If you open a browser on http://localhost:7681 , you will see the subscribed messages from the threads in this app via the broker app.
