Esempio

class CSockThread : public CWinThread
{
public:
   SOCKET m_hConnected;

protected:
   CChatSocket m_sConnected;

   // remainder of class declaration omitted.

BOOL CSockThread::InitInstance()
{
   // Attach the socket object to the socket handle
   // in the context of this thread.
   m_sConnected.Attach(m_hConnected);
   m_hConnected = NULL;

   return TRUE;
}

// This listening socket has been constructed
// in the primary thread.
void CListeningSocket::OnAccept(int nErrorCode)
{
   UNREFERENCED_PARAMETER(nErrorCode);

   // This CSocket object is used just temporarily
   // to accept the incoming connection.
   CSocket sConnected;
   Accept(sConnected);

   // Start the other thread.
   CSockThread* pSockThread = (CSockThread*)AfxBeginThread(
      RUNTIME_CLASS(CSockThread), THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED);
   if (NULL != pSockThread)
   {
      // Detach the newly accepted socket and save
      // the SOCKET handle in our new thread object.
      // After detaching it, it should no longer be
      // used in the context of this thread.
      pSockThread->m_hConnected = sConnected.Detach();
      pSockThread->ResumeThread();
   }
