Completion port & winsock problem.

[Nadav]

Hi,

Introduction:
*************************
I am developing communication infrastructure for a streaming video server,
to achieve optimal performance I use IO Completion ports & a thread pool in
combination with winsock MsAPI ( e.g. ConnectEx, AcceptEx, … ), sending data
through sockets is done with Read/WriteFile.

The problem:
*************************
Upon IO Completion of any kind ( e.g. Socket Connection completion , socket
data reception , … ) I get double completion notifications, in other words:
GetQueuedCompletionStatus returns twice for the same IO operation…

I guess I am not the first encountered this problem…
Does someone have a clue what may cause this problem?

Any pointer, comment or remark would be appreciated.

I don't know why you think that.

You will probably need to post the smallest snippet of code that you can get
to exhibit the problem in a more appropriate group, e.g.

microsoft.public.win32.programmer.kernel
