d、接受SOCKET连接并进行完成端口绑定

VOID IoHandler::ProcessAcceptedSessionList()
{
SESSION_LIST_ITER   it;
Session      *pSession;

// 立加俊 己傍茄 技记甸阑 罐酒敌 烙矫 府胶飘肺 颗辫
m_pAcceptedSessionList->Lock();
m_pTempList->splice( m_pTempList->end(), *m_pAcceptedSessionList );//将m_pAcceptedSessionList 合并到TEMPLIST
m_pAcceptedSessionList->Unlock();

// 立加俊 己傍茄 技记俊 措茄 贸府
for( it = m_pTempList->begin(); it != m_pTempList->end(); ++it )
{
   pSession = *it;

   // 弥绊悼立荐甫 檬苞窍绰 版快 角菩
   if( m_numActiveSessions >= m_dwMaxAcceptSession )
   {
    printf( "connection full! no available accept socket!\n" );
    m_pTempList->erase( it-- );
    ReuseSession( pSession );
    continue;
   }

   // IOCP绑定
   CreateIoCompletionPort( (HANDLE)pSession->GetSocket(), m_hIOCP, (ULONG_PTR)pSession, 0 );

   // Recv俊 角菩窍绰 版快 贸府
   if( !pSession->PreRecv() )
   {
    m_pTempList->erase( it-- );
    ReuseSession( pSession );
    continue;
   }

   //--------------------------------
   // 己傍利栏肺 立加等 技记 贸府
   //--------------------------------

   // 匙飘亏 坷宏璃飘 积己 夸没
   NetworkObject *pNetworkObject = m_fnCreateAcceptedObject();
   assert( pNetworkObject );

   // 匙飘亏 坷宏璃飘 官牢爹
   pSession->BindNetworkObject( pNetworkObject );

   // 立加矫 檬扁拳 棺 NetworkObject肺 立加 烹瘤
   pSession->OnAccept();

   // 悼立荐 刘啊
   ++m_numActiveSessions;
}

if( !m_pTempList->empty() )
{
   // 立加俊 己傍茄 技记甸阑 ActiveSessionList俊 眠啊
   m_pActiveSessionList->Lock();
   m_pActiveSessionList->splice( m_pActiveSessionList->begin(), *m_pTempList );
   m_pActiveSessionList->Unlock();
}
}

PreRecv() 的动作判断SOCKET是否继续有效

BOOL Session::PreRecv()
{
WSABUF wsabuf;

m_pRecvBuffer->GetRecvParam( (BYTE**)&wsabuf.buf, (int&)wsabuf.len );

ZeroMemory( &m_recvIoData, sizeof(OVERLAPPEDEX) );

m_recvIoData.dwOperationType = RECV_POSTED;

int ret = WSARecv( GetSocket(), &wsabuf, 1, &m_recvIoData.dwIoSize, &m_recvIoData.dwFlags, &m_recvIoData, NULL );

if( ret == SOCKET_ERROR && WSAGetLastError() != WSA_IO_PENDING )
{
   return FALSE;
}

return TRUE;
}
