Quickstart

Connect to a server

sio::client h;
h.connect("http://127.0.0.1:3000");

Emit an event

// emit event name only:
h.socket()->emit("login");

// emit text
h.socket()->emit("add user", username);

// emit binary
char buf[100];
h.socket()->emit("add user", std::make_shared<std::string>(buf,100));

// emit message object with lambda ack handler
h.socket()->emit("add user", string_message::create(username), [&](message::list const& msg) {
});

// emit multiple arguments
message::list li("sports");
li.push(string_message::create("economics"));
socket->emit("categories", li);

Bind an event

Bind with function pointer

void OnMessage(sio::event &)
{

}
h.socket()->on("new message", &OnMessage);

Bind with lambda

h.socket()->on("login", [&](sio::event& ev)
{
    //handle login message
    //post to UI thread if any UI updating.
});

Bind with member function

class MessageHandler
{
public:
    void OnMessage(sio::event &);
};
MessageHandler mh;
h.socket()->on("new message",std::bind( &MessageHandler::OnMessage,&mh,std::placeholders::_1));

Using namespace

h.socket("/chat")->emit("add user", username);
