How can I store a boost::bind object as a class member?

Question

I\'m writing an application that uses boost::asio. Asio\'s async_receive (or async_read) is invariably shown using a boost::bind

Answer 1

The return type of boost::bind is a boost::function. Here's a quick example using a very simple function:

double f(int i, double d) { 
    cout << "int = " << i << endl; 
    return d; 
} 

boost::function bound_func = boost::bind(f, _1, 1.234); 
int i = 99; 
cout << bound_func(i) << endl;

In your case the function has this type:

boost::function f;
