I want to make a scripting engine, with a function that associates a string with a function, so when the parser comes accross that string, it executes the function that is associated with it in a table. I know this can be done with function pointers, but... what are function pointers? It would be a great help if someone would give me some code or a link. Thanks.

// Here''s my example functionbool SomeFunc(int a, int b) { // Do Something return false;}// Here''s a function pointerbool (*FuncPointer)(int, int) = SomeFunc;// Now we call it like normal (the following are both the same pretty much)SomeFunc(58,291);FuncPointer(58,291);

hm. I thought I tried that... but thanks! thats realllllly cool.

Just as an added thought ... you may want to typedef your function pointer. It will make your life a little easier, especially if you ever have the requirement to typecast.

You might want to use a std::map<> structure to map out your functions for your scripting thing...

ie

std::map<std::string,bool (*pFunc)(int&, int& )> FunctionMap;

Just a hint
