We could have changed it to accept boost::function instead, but that means that users of our class would need to understand how function works [2] too, rather than just knowing about the requirements for the observer type. now, both function pointers, function objects, and instances of boost::function can be passed to add_observer, without any changes to existing user code. boost::function<void(int)>.

There are several advantages to using Boost.Function rather than function pointers:. the possibility to use binders, such as Boost.Bind and Boost.Lambda. Each of these advantages favor using Boost.Function over the C-style callbacks that have been prevalent in solving this type of problem.. Only when the small additional cost of using Boost.Function compared to function pointers is prohibitive should the function pointer technique be considered.. Boost.Function was created by Douglas Gregor.

Thinking in C plus plus (P14)

Fortunately, the compiler takes care of all the bookkeeping for you and ensures that all the function pointers in all the VTABLEs of a particular class hierarchy occur in the same order, regardless of the order that you may override them in derived classes.. Once the address of the proper function pointer in the VTABLE is calculated, that function is called. Because the VPTR determines the virtual function behavior of the object, you can see how it’s critical that the VPTR always be.

Function pointers are also slightly more efficient when invoked, because where a function pointer is invoked directly, Boost.Function may require two calls through function pointers. Although these are potential disadvantages of Boost.Function, it is not very often that these are real-world issues.
