Getting PID With C++ shell()?

I'm working on a C++ game, which I want to play music in the beginning. This is a sample of my code so far:

int main() {
    // Gets user's name
    system("clear");
    system("afplay ~/music.mp3 &>/dev/null &");
    string name;
    cout << "###################\n";
    cout << "# Enter your name #\n";
    cout << "###################\n";
    cin >> name;

    // Greets user
    system("clear");
    cout << "So, your name is " << name << "?\n";
    system("sleep 1.5");
    cout << "Greetings, and welcome to the world of NULL!\n\n";
    system("kill $!");

    return 0;
}

However, the kill $! isn't killing, or stopping the afplay music. I think it is because the system("afplay ~/music.mp3 &>/dev/null &"); isn't outputting the PID into $!.

How can I kill afplay or at least get its PID so I can kill it?

I'm on a Mac and I'm new to C++...

WARNING: This is a bad practice; it could kill important processes and kills all, so it may stop tasks that the user was using!

Solution

  • Apple's manual page says that you may just call

    killall afplay
