c++协程1 (boost::coroutine)

#include <iostream>#include <boost/coroutine/all.hpp>  using namespace boost::coroutines;//coroutine函数void cooperative(coroutine<void>::push_type &sink){std::cout << "Hello";//之所以能够执行是因为重载了操作符()//返回main()函数继续运行sink();std::cout << "world";//执行完毕，返回main继续执行}int main(){//c++11新特性：统一初始化//source对象由于是pull_type类型，所以会马上调用cooperative, push_type类型不会立即执行coroutine<void>::pull_type source{ cooperative };std::cout << ", ";//返回cooperative函数继续执行source();std::cout << "!";std::cout << "\n";}
