socket.on("disconnect", handler) not working

[RobertHolscher]

In the documentation you write that the disconnect event is triggered when the connection is lost with the server. I am trying to use that with the arduino sketch but the compiler says: No matching function for call to 'SocketIoClient::on(const char [11], void(&)())'

The call I am using is webSocket.on("disconnect", disconnectevent);

The disconnectevent is the handler Am I using it wrongly ?

Do you have a matching function called "disconnectevent"? In my sketch it would look like this:

void disconnected(const char * payload, size_t length) {
    // do something when disconnected....
}

webSocket.on("disconnect", disconnected);

Thank you, forgot to put in the (const char * payload, size_t length), overlooked that. Thanks for your reply

It compiles ok now , case closed
