Comment(by hamish):
I tried GetProcessId again and it works. Not sure what happened when I
tried it before, but I think I might have messed up the calling convention
by not defining _WINNT_VER before including windows.h (I noticed this time
when I was testing GetProcessId in runProcess.c that I got a warning that
it was GetProcessId's sig was not defined if I did not define _WINNT_VER).
Anyway I stuck getProcessId into Win32 package where it belongs and it
works fine.
I have updated the patch with this and your other suggestions and the new
version is here
https://github.com/hamishmack/packages-
process/tree/Ticket-3994-GetProcessId
and
https://github.com/hamishmack/packages-Win32/tree/Ticket-3994-GetProcessId
I also added a test case that makes sure "sleep 10" can be interrupted.
The flags are in a separate header so they can easily be #included in both
the .hs and the .c (runProcess.h did not work when #included in the .hs)
