Hi Experts,

          Could you please let me know if any LWS function is available to check whether the WebSocket connection is in progress or not?

Thanks, Rajasekhar.

Generally speaking you need to follow the callbacks on the wsi to understand its state. If you want a flag you can look at later you can keep your own flag that has the meaning you want. But it's often a sign of other problems if you don't know very well the state of the connection already. For example the connection can close at the socket level at any time, and then lws will destroy everything about the connection. If you think you're going to come along later asynchronously and ask it if it is "in progress" whatever that means, you may be in for a surprise because the whole thing is deleted already.
