How to pass PWOHandleArray to WaitForMultipleObjects

[Alexey Karpenko]

Hi all,

Could anybody please tell me what's wrong with this code? When using
WaitForSingleObject instead of WaitForMultipleObjects and pass only one
handle it's ok. But when I try to pass an array nothing happens as needed.

procedure TTrackingThread.Execute;
var
Handles: array[0..5] of THandle;
begin
Handles[0] := FAkDirWatch.FhFileName;
Handles[1] := FAkDirWatch.FhDirName;
Handles[2] := FAkDirWatch.FhAttributes;
Handles[3] := FAkDirWatch.FhSize;
Handles[4] := FAkDirWatch.FhLastWrite;
Handles[5] := FAkDirWatch.FhSecurity;

while not Terminated do begin
case WaitForMultipleObjects(6, @Handles, False, INFINITE) of
...

Could anybody guide me? I'm sure it must work, but it doesn't!

Many thanks in advance,
Alexey Karpenko

Not a very informative problem description. What is happening? Does the Wait
not wait? If not, what does it return? If one of the handles in your array
is in a signalled state already the wait would of course return immediately.

Note: I'm unable to visit the newsgroups every day at the moment,
so be patient if you don't get a reply immediately.

Peter, thank you for your interest. I've already managed this problem. It
returned WAIT_FAILED, because some of the handles in the array were zeros.
Now it's ok.

Thank you again,
