We currently have one pipe handle and two OVERLAPPED structs. We use events in the OVERLAPPED structs to find out when the I/O is complete. In comment 2 I was realizing that we can't associate those events with an I/O completion port. But I guess you're saying we can stop using events and just compare the addresses of the OVERLAPPED structs to figure out what happened.
