I get the following error message:
(Project Directory)\boostfunctest.cpp(11) : error C2079: 'MyFunc' uses
undefined class 'boost::function'
       with
       [
           Signature=void (__stdcall *)(int *)
       ]
boost::function requires a function signature.
If you have a function pointer, you need to use

#include <boost/type_traits/remove_pointer.hpp>

template<class FunctionPointerType>
void foo() {
    boost::function<typename 
boost::remove_pointer<FunctionPointerType>::type> f;
}
