A virtual call can be performed knowing only the addresss of a v-table entry and the type of the virtual function. On most platforms, a v-table entry is equivalent to a function pointer, and the type of that function pointer can be determined from the member pointer type. However, there...

int (*x)() is not a pointer to member function. A pointer to member function is written like this: int (A::*x)(void) = &A::f;. 3. class A { public: void call(); private: void printH(); void command(std::string a, std::string b, void (A::*func)()); }; void A:...

On MSVC, there is also a different type for each of the three different calling conventions: __cdecl, __stdcall, and __fastcall. You make your function pointer point to a function float some_func(int, char *) like this: my_func_ptr = some_func; When you want to invoke the function...
