именно в WinsockAPI ?

Вот так, например:

function TThSC.fWaitEvent(aTimeOut:Cardinal): Cardinal;
var
wne: WSANETWORKEVENTS;
begin
WSAResetEvent(fEvent);
WaitForSingleObject(fEvent,aTimeOut);
WSAEnumNetworkEvents(fSocket,fEvent,@wne);
Result := wne.lNetworkEvents;
Exit;
end;

procedure TThSC.Execute;
var
WaitResult: Cardinal;
begin
repeat
WaitResult := fWaitEvent(1);

if WaitResult=WSA_WAIT_FAILED then Terminate;
if WaitResult=WSA_WAIT_TIMEOUT then continue;
if Terminated then Exit;

if (WaitResult and FD_READ)=FD_READ then
begin
onReceive;
end;
if (WaitResult and FD_CLOSE)=FD_CLOSE then
begin
OnClosed;
Terminate;
break;
end;
if (WaitResult and FD_WRITE)=FD_WRITE then
begin
OnWrite;
( WaitResult = WAIT_FAILED) Вот так, например:

function TThSC.fWaitEvent(aTimeOut:Cardinal): Cardinal;
var
wne: WSANETWORKEVENTS;
begin
WSAResetEvent(fEvent);
WaitForSingleObject(fEvent,aTimeOut);

until (WaitResult = WAIT_FAILED) or Terminated;
end;
