Using CoWaitForMultipleHandles

Continuing from

Pausing execution of a Thread WITHOUT sleeping?

How do I use the CoWaitForMultipleHandles routine, as Lars Truijens suggested? I found the routine in the SyncObjs unit, however I get "undeclared identifier" when trying to call it? The IDE Insight does not bring anything up either? And yes, I have added SyncObjs to my Uses clause.

I can't see what other info I need to include - however feel more than free to ask for more in开发者_如何学编程fo!

You can't call this function from SyncObjs, because it hasn't been declared in interface section. But TEvent.WaitFor actually calls CoWaitForMultipleHandles. Did you try it?

And please note its constructor declaration:

{ Specify UseCOMWait to ensure that when blocked waiting for the object
  any STA COM calls back into this thread can be made. }
constructor Create(UseCOMWait: Boolean = False);
