Hi,

how is it possible to get the CAsyncSocket-Handle in the OnAccept-
method? I don`t want to install one thread for each connection - I`ve
one thread for all http-connections.

void ConnSoc::OnAccept(int nErrorCode)
{
//doing some error stuff

// New connection is being established
CAsyncSocket soc; //using threads / detach / attach

if(!Accept(soc)) //error-handling

CAsyncSocket::OnAccept(nErrorCode);
}

If you install a thread for each connection, a new socket is installed
with detach / attach handling. But what`s a suitable solution using
only one thread?

class ConnSoc : public CAsyncSocket
class SocketThread : public CWinThread

At the moment I`ve installed a protected function within SocketThread
virtual ConnSoc * GetSocket() {ASSERT(FALSE); return NULL; }

best regards
Bernd

In the OnAccept function of the listener socket you need to create a new
object derived from CAsyncSocket, like CDataSoc, and pass it to the listener
socket Accept:

void ConnSoc::OnAccept(int nErrorCode)
{
CDataSoc* pSocket = new CDataSoc();
Accept(*pSocket);

This new socket will run in the current thread.
