What happens when you close a c++ console application

Question

I guess the question says it all, but, what happens if someone closes a c++ console app? As in, clicks the \"x\" in the top corner. Does it instantly close? Does it throw so

Answer 1

Closing a c++ console app with the "x" in the top corner throws an CTRL_CLOSE_EVENT which you could catch and process if you set a control handler using the SetConsoleCtrlHandler function. In there you could override the close functionality and perform whatever you wished to do, and then optionally still perform the default behavior.
