That just seems very strange.

You have two threads: one for managed code (C#) and the other for
unmanaged code (your embedded app).  You want the C# thread to block on
an event until signaled by the unmanaged thread.  The C# thread will
then use an internal call to obtain a pointer to an unmanaged signal

Why? :-)

It makes more sense for the unmanaged thread to do everything (setup,
add signal handlers) than to mix the threads in the fashion described

If you instead want to ensure that the C# code isn't executed until the
signal handlers are in place, then just don't start the C# thread until
the signal handlers are in place. :-)

The KISS principal is your friend.  Follow it.  :-)
