Code Sinnpet:

int CreateaTCPSocket()
{
               int iSockID =  ACE_OS::socket(......);
               ACE_OS::set_flags(iSockID,O_NONBLOCK);
               ACE_OS::bind();
               if (ACE_OS::connect(iSockID ,....) < 0)
               {
                     if (ACE_OS::select(.....,timeout) <= 0)
                     {
                        return INVALID_HANDLE;
                     }
                }
                return iSockID;
}

My question is when connect is failed for non-block error and select is called and say select return success then again we need to call connect or select function internal do connect?
