Async socket?

[MiLa]

Hi,

What is the best way to do a asynchronous socket (for reading socket)
in application without userinterface?

Those WSAAsyncXXX methods want that window handle ...

Any sample or hint?

Regards

You'll alway need a window if you wan't asynchronous sockets, because after
these functions have done their job, they have to inform you about it, and
the only way is to send a message to a window.

But you can use a hidden window! ( w/o WS_VISIBLE )

Ok, Thanks for answering.
I thought also that hidden windows but it sounded a little bit "exaggerated"
first.
How about Berkeley sockets? Can they use asynchronous reading?
Or can I use overlapping reading with WinSockets?

You use the same method as is used on Unix. Use the select function.
It can test a set of sockets for information to send/read and will
furthermore allow you to have a timeout.

This is covered by any Unix books on networks/sockets

Overlapped ReadFile and WriteFile operations, using the SOCKET as a HANDLE.
