Somehow GenerateConsoleCtrlEvent() return error if you call it for another process, but you can attach to another console application and send event to all child processes.

void SendControlC(int pid)
{
    AttachConsole(pid); // attach to process console
    SetConsoleCtrlHandler(NULL, TRUE); // disable Control+C handling for our app
    GenerateConsoleCtrlEvent(CTRL_C_EVENT, 0); // generate Control+C event
}
