is it possible to get direct access to a function object encapsulated in boost::function ?

If you know that type of the function object, you can use target.

And is it possible to determine whether boost::function has indeed stored a function object rather than, say, a function pointer ?

You can get the typeid of the type that a boost::function contains using the function target_type. #include <iostream> #include void f() { std::cout << "Calling f" << std::endl; } int main() { boost::function func = &f; if(func.target_type() == typeid(void(*)())) { func(); } if(void(**target)() = func.target()) { (*target)(); } } In Christ, Steven Watanabe
