With an IOCP, you can give the IOCP a *connected* socket and the IOCP
will call you back when a read occurs.
But you cannot pass in an *unconnected* socket in the listen state, for
the IOCP is not capable of calling you back when an incoming connection
occurs and you need to call accept().
The docs say the following functions can be used with an IOCP;
ConnectNamedPipe
DeviceIoControl
LockFileEx
ReadDirectoryChangesW
ReadFile
TransactNamedPipe
WaitCommEvent
WriteFile
So, as you can see, it doesn't seem possible to use an IOCP to handle
incoming connections.
FYI, libiocp 1.03 was put on the site last night. I'm going to add some
example code next, and then maybe integrate the listen/accept solution
I've written.
Use AcceptEx.
