Hello,

I have a question, one might be able to aswer.
I am using an the winsock api through VBA in Excel to communicate with
a Haskell server.
The Haskell server allows multiple clients. All incoming data and
computed results are multiplexed to all clients.
Therefore the Excel client has somehow to react an some 'action' on
the channel. Is the a possibility to generate an event, whenever data
is arriving on the channel? Of course, this behavior must be non-
blocking.

In my opinion, polling would be a valid but bad solution for this
problem.

Thanks in advance for your suggestions,

regards,
Markus
