c++ - boost::bind 作为左值对象

Question

有没有办法做这样的事情(MS VS 2008)？

boost::bind mybinder = boost::bind(/*something is binded here*/);
mybinder(/*parameters here*/); // <--- first call
mybinder(/*another parameters here*/); // <--- one more call

我试过了

int foo(int){return 0;}

boost::bind<int(*)(int)> a = boost::bind(f, _1);

但它不起作用。

Answer 1

int foo(int){return 0;}
boost::function<int(int)> a = boost::bind(f, _1);
