Exit application while stdin blocking on windows

I have an application, which reads data from standard input using getline() in a thread. I want to close the application from the main thread, while getline still block the other thread. How can this be achieved?

I have tried so far:

• freopen stdin, but it is blocked by internal lock
• destructing the thread, which calls abort()
• putback an Eof, line end to std::cin, which also blocked

I don't want to force the users to have to press ctrl-Z to close stdin and the application.

Example code:

#include <iostream>
#include <thread>
#include <string>
#include <chrono>

int main(int argc, char *argv[])
{
    bool stop = false;
    std::thread *t = new std::thread([&]{
        std::string line;
        while (!stop && std::getline(std::cin, line, '\n')) {
            std::cout << line;
        }
    });

    std::this_thread::sleep_for(std::chrono::seconds(1));

    stop = true;
    // how to stop thread or make getline to return here?

    return 0;
}
