The IFWXOverlapped interface is used to hook into the I/O completion port of the Firewall service, for asynchronous I/O with Win32 files. You can hook into the completion port thread pool by linking a handle to the completion port (call the IFWXFirewall::HookToCompletionPort method). Overlapped Win32 functions must then be called with the Winsock structure OVERLAPPED returned by this interface.
