Detailed Description

Starts a socket connect operation, connecting to a remote endpoint.

Callback will be called when the given socket is connected to ipAddress.
Socket library can be used to create a Socket but the socket should be created with SC::SocketFlags::NonBlocking and associated to the event loop with SC::AsyncEventLoop::associateExternallyCreatedTCPSocket.
Alternatively SC::AsyncEventLoop::createAsyncTCPSocket creates and associates the socket to the loop.

// Assuming an already created (and running) AsyncEventLoop named eventLoop
// ...
SocketIPAddress localHost;
SC_TRY(localHost.fromAddressPort("127.0.0.1", 5050)); // Connect to some host and port
AsyncSocketConnect connect;
SocketDescriptor   client;
SC_TRY(eventLoop.createAsyncTCPSocket(localHost.getAddressFamily(), client));
connect.callback = [&](AsyncSocketConnect::Result& res)
{
    if (res.isValid())
    {
        // Do something with client that is now connected
        console.printLine("Client connected");
    }
};
SC_TRY(connect.start(eventLoop, client, localHost));

Member Typedef Documentation

◆ CompletionData

◆ Result

using SC::AsyncSocketConnect::Result = AsyncResultOf<AsyncSocketConnect, CompletionData>

Callback result for AsyncSocketConnect.

Member Function Documentation

◆ start()

SC::Result SC::AsyncSocketConnect::start	(	AsyncEventLoop &	eventLoop,
		const SocketDescriptor &	socketDescriptor,
		SocketIPAddress	ipAddress
	)

Starts a socket connect operation.

Callback will be called when the given socket is connected to ipAddress.

Parameters

eventLoop	The event loop where queuing this async request
socketDescriptor	The socket needing to connect to the ip address
ipAddress	A valid ip address to connect to

Returns: Valid Result if the request has been successfully queued

Member Data Documentation

◆ callback

Function<void(Result&)> SC::AsyncSocketConnect::callback

Called after socket is finally connected to endpoint.
