subject: Ctrl-Break / Ctrl-C Checking

Hello All!

How do I turn-off Ctrl-Break / Ctrl-C checking in my program using the
Borland compiler.  The signal function (which I thought would do the trick)
did not work as anticipated.  I'm simply calling:

signal(SIGINT, SIG_IGN);    // Ctrl-C ignore
signal(SIGBREAK, SIG_IGN);  // Ctrl-Break ignore

One caveat listed in the Library Reference states, "Special care must
be taken when using the signal function in a multithread program.  The
SIGINT, SIGTERM, and SIGBREAK signals can be used only by the main thread
in a non-PM application."

I have written a multithread terminal "test" program using my
low-level ASYNC library.  I can post the source if needed.  Thanks...
