coroutine

With Boost.Coroutine it is possible to use coroutines in C++. Coroutines are a feature of other programming languages, which often use the keyword yield for coroutines. In these programming languages, yield can be used like return. However, when yield is used, the function remembers the location, and if the function is called again, execution continues from that location.

#include <boost/coroutine/all.hpp>
#include <iostream>

using namespace boost::coroutines;

void cooperative(coroutine<void>::push_type &sink)
{
  std::cout << "Hello";
  sink();
  std::cout << "world";
}

int main()
{
  coroutine<void>::pull_type source{cooperative};
  std::cout << ", ";
  source();
  std::cout << "!\n";
}

using namespace boost::coroutines;
void cooperative(coroutine<int>::push_type &sink)
{
    int i=0;
  sink(++i);
  sink(++i);
}

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    coroutine<int>::pull_type source{cooperative};
    qDebug()<<source.get();
    if(source){
        qDebug()<<source().get();
    }
    return a.exec();
}
//1 2

#include <boost/coroutine/all.hpp>
#include <stdexcept>
#include <iostream>

using boost::coroutines::coroutine;

void cooperative(coroutine<void>::push_type &sink)
{
  sink();
  throw std::runtime_error("error");
}

int main()
{
  coroutine<void>::pull_type source{cooperative};
  try
  {
    source();
  }
  catch (const std::runtime_error &e)
  {
    std::cerr << e.what() << '\n';
  }
}
