Hello,

Is the following code (from Indy 9) safe, or is it possible for the 
TCPServer->Threads 'Count' to change between the LockList() and UnlockList() 
calls?   (this code is in a message handler function that is called as the 
result of a PostMessage, so it runs in the context of the main thread)


   TList *pThreadList = TCPServer->Threads->LockList();
   int Count = pThreadList->Count;
   for ( int c=0; c<Count; ++c )
   {
      TIdPeerThread *pPeerThread = static_cast<TIdPeerThread 
*>(pThreadList->Items[c]);
      // do something with the thread
   }
   TCPServer->Threads->UnlockList();

- Dennis
