According to David Xiao on 4/20/2007 9:49 AM:
> In win32 sub-system there is no signal or sig-stack facilities. I am quite curious how cygwin1.dll can do that? What's the mysterious part of it?
> 
> As I knew, user-mode thread library such as pthread (POSIX thread) can be implement in use of signal. So signal facilies emulation is quite essential part to full implement a POSIX sub-system like cygwin does.
> 
> I wish some can share with experience on this topic: How does cygwin provide signal facilities?
