Basic multithread testing. We may use something like this to run a camera on our 2015 FRC robot.

threadTest.cc

//g++ test.cc -std=c++11 -lpthread

#include <iostream>
#include <thread>
#include <chrono>
using namespace std;

void f() { //function to run in 2nd thread
    for (int i = 0; i < 10; ++i)
    {
        cout << "Thread 2\n";
        this_thread::sleep_for(chrono::seconds(5));
    }
}
 
int main() {
    thread t(f); //2nd thread
    for (int i = 0; i < 10; ++i)
    {
        cout << "Thread 1\n";
        this_thread::sleep_for(chrono::seconds(1));
    }
    t.join(); //prevents interrupt when Thread 1 finishes before Thread 2
}
