Send Ctrl+C event to any Windows window

Sometimes you want to close a window on Windows with the Ctrl+C combination, or to raise that event for some other reason. On Windows you can write a small program like this:

#include <windows.h>
#include <stdio.h>

int main(int argc, char* argv[])
{
 int pid = atoi( argv[1] );
 printf("kill in console %d", pid);

 FreeConsole();
 if (AttachConsole(pid))
 {
     SetConsoleCtrlHandler(NULL, true);
     GenerateConsoleCtrlEvent(CTRL_C_EVENT, 0);
     FreeConsole();
     SetConsoleCtrlHandler(NULL, false);
 }

 return 0;
}

As the argument you pass the PID of the target window’s process (you can look it up in the system monitor).
