Is there such event as "Closing console" in C++?

Is there any event like in C# "FormClosing" but in C++ as Console closing where I can execute some code before the Console close? (In my case, I'd like to create a directory with the input of the user before the console is closed completely).

My guess is that you want to get the Event when clicking the [X]

BOOL WINAPI HandlerRoutine( DWORD eventCode )
{
  switch( eventCode )
  {
      case CTRL_CLOSE_EVENT:
      // do your thing
      return FALSE;
      break;
   }

  return TRUE;
}

Is that what you're looking for?

You also need to enable the Handler:

int main()
{
    SetConsoleCtrlHandler( HandlerRoutine , TRUE );
    getch();
}

A closing console effectively kills your application. In windows I'm unsure of the ability to trap this, but in linux you could trap the KILL signal?

If you want to close the console, then you can use FreeConsole();

If you then further want to open the console again, you can use AllocConsole();
