Overlapped

Hi,

What does the "overlapped" word means in windows programming?
I've read about overlapped structures, functions?!

What does it mean?

Thanks!

It refers to the ability to overlap input/output and computation.

In some environments (like the ones provided by Java and 'nix, 'nux or 'pux
<BSEG>) applications _generally_ wait idle while a read or write is pending.
Win32's asynchronous or overlapped mode allows an application to initiate a
read or write, go on to do something else while it completes and then
receive a notification when it is done.

Regards,
Will
