Exceptions and POSIX signals

NTDEV
1

Hi all

I’m working on a POSIX subsystem for Windows NT, and I’m currently trying
to figure out how can signals be implemented. I’ve looked at similar
projects, such as Cygwin, but I wasn’t satisfied with their implementations
(mainly because they are limited to the array of calls exposed by Win32). I
casually noticed a similarity between signal semantics and exception
semantics, so I’m here for some insight…

My main concern is: can exceptions be cleanly raised in foreign threads?
i.e. inter-process? or should I use something completely different, for
example APC? any Unix wizards out there can shed some light?

Do SetThreadContext to the signal raiser code.
