Threads

To use the multithreading interface of C++ you need the header <thread>.

Creation

A thread std::thread represents an executable unit. This executable unit, which the thread immediately starts, gets its work package as a callable unit. A callable unit can be a function, a function object or a lambda function:

Thread creation

// threadCreate.cpp 
...
#include <thread>
...
using namespace std;

void helloFunction(){
  cout << "function" << endl;
}

class HelloFunctionObject {
public:
  void operator()() const {
    cout << "function object" << endl;
  }
};

thread t1(helloFunction);                      // function

thread t3([]{ cout << "lambda function"; });   // lambda function

Lifetime

The creator of a thread has to take care of the lifetime of its created thread. The executable unit of...
