What exactly is the effect of Ctrl-C on C++ Win32 console applications?

Question

1. Is it possible to handle this event in some way?
2. What happens in terms of stack unwinding and deallocation of static/global objects?

Answer 1

Ctrl-C in console application will generate a signal. The default handler of this signal calls ExitProcess to terminate the application. You can override this behaviour by setting your own handler functions for the signal using SetConsoleCtrlHandler function.
