in reply to Re^2: Signals vs. Windows
in thread Signals vs. Windows

So, the problem restated is, I guess, how do I interrupt a thread from an I/O operation?

1. dont use blocking I/O, use overlapped/async I/O

2. use Native API, create an alertable *synchronous* file handle using NtCreateFile, post a timer APC to the blocked thread with SetWaitableTimer, the APC will call CancelIo from within the blocked thread, and the blocked I/O will unblock.
