C++ .Net UDP Socket Endpoint question

[keelo]

I have a small c++ .net program that is intended to be a simple UDP server; however, I just want to start blasting out packets when a connection is made.

After setup,

Socket^ socket = gcnew Socket(AddressFamily::InterNetwork, SocketType::Dgram, ProtocolType::Udp);
IPEndPoint^ ipep = gcnew IPEndPoint(IPAddress::Any, 54321);

socket->Bind(ipep);

while(true)
{
array<unsigned char>^ message = gcnew array<unsigned char>(1024);
EndPoint^ Remote = (EndPoint^) gcnew IPEndPoint (IPAddress::Any, 0);

int recv = socket->ReceiveFrom(message, Remote);

So, the above blocks until a message arrives, then I can write to the endpoint.

What I am trying to understand is, is what is the proper combination of listen/accept/etc... can I block on until I get a connection (endpoint) which I can start writing to.

Pulling what's left of my hair out.
