Exploring C++ threads

In the previous section, we learned how POSIX provides support for threads. In this section, we will discuss C++ threads, which are largely inspired by POSIX threads. They provide similar functionality while simplifying the APIs in some ways, and also providing type safety.

The basics of C++ threads

To demonstrate the simplicity of C++ threads, the following example, like the first example in this chapter, creates two threads and then waits for them to finish executing:

#include <thread>
#include <iostream>

void mythread()
{
    std::cout << "Hello World\n";
}

main()
{
    std::thread t1{mythread};
    std::thread t2{mythread};

    t1.join();
    t2.join();
}
