Cmd Pipeline function pointer

This is kind a bump, and Update to the Question.

-I figured out how to pass funtions as arguments.

class Cmd_Pipeline {
public:
	Cmd_Pipeline() {}
	~Cmd_Pipeline() {}
	bool IsCmd(string& text);
	int Run(string text) {
		int size = Labels.size();
		for(int i=0;i < size; i++) {
			if(text == Labels)
                cout << "nice!" << endl;
		}
		return 0;
	}

	void AddCmd(string label,int (*Function)()) {
		Labels.push_back(label);
		pFunctions.push_back(Function);
	}
private:
	typedef int (*pFunctionMember)();
	vector Labels;
	vector pFunctions;
};

Cmd_Pipeline cmdpipe;

int Function1() {
	cout << "function1 was Run!" << endl;
return 0;
}

int main (int argc,char** argv) {
	bool bRunProgram = true; //keep scanning scanf
	string scanBuffer;//buffer for scanf
	
	cmdpipe.AddCmd("function1",&Function1);
	cmdpipe.Run("function1");
    
	while(bRunProgram) { 
		cin >> scanBuffer;
		transform(scanBuffer.begin(),scanBuffer.end(),scanBuffer.begin(),toupper); //makes commands NOT case dependent
		if(scanBuffer == "EXIT") 
			bRunProgram = false;
		else
			bRunProgram = true;
		scanBuffer.clear();
	}

return(0);
}
 

This works great! however, If I were to add a add Under Funtion1''s Body

class Tmp {
public:
	Tmp() { cmdpipe.AddCmd("TmpFunc1",&Tmp::Func1); } //this??
	~Tmp() { }
	int Func1() { cout << "Tmp Class Func1 called!" << endl; }
};
 

main.cpp(14): error C2664: ''Cmd_Pipeline::AddCmd'' : cannot convert parameter 2 from ''int (__thiscall Tmp::* )(void)'' to ''int (__cdecl *)(void)''

I understand this is a class funtion, so I added this to the Cmd_Pipeline class

private:
//Add this line,
typedef int (Cmd_Pipeline::*pClassFunctionMember)() pClassFunction;
//Now I can define a vector of ClassFunctions for CmdPipeline

However, I cant overload AddCmd() because I don''t know how to pass class funtion as arguments.

I guessed this
void AddCmd(string label,int (Cmd_Pipeline::*Function)()) { }

but it looks for a member of Cmd_Pipeline called Function*...

So right now I have two objectives.
1-figure out how to pass in a class function into a function, or how to define a function argument of a function.
2-make it so the function can return any type, or have any number of args

Pointer to member syntax is gross. Try a space between the * and the name?

I use Boost.Function, it will let you use member functions or regular functions, and you can call them like a normal function.

int (*func)(int, string&)

defines a function pointer that returns an integer and takes a string reference.

You''ll have to go with some sort of generic type like a string for everything to pull this off. C++ sucks like that.

I got this from www.function-pointer.org

class TFunctor {
public:
	virtual void operator()(const char* string)=0;  // call using operator

	virtual int operator()()=0;  // call using operator

};
template <class TClass> class Functor : public TFunctor {
private:
	void (TClass::*fpt0)(const char*);   // pointer to member function

	int (TClass::*fpt1)();
	TClass* pt2Object;                  // pointer to object

public:
	Functor(TClass* _pt2Object, void(TClass::*_fpt)(const char*)) { pt2Object = _pt2Object;  fpt0=_fpt; };
	Functor(TClass* _pt2Object, int(TClass::*_fpt)()) { pt2Object = _pt2Object;  fpt1=_fpt; };
    virtual void operator()(const char* string) { (*pt2Object.*fpt0)(string);};  // execute member function

	virtual int operator()() { (*pt2Object.*fpt1)();return(0);};
   };

Only problem is you need to define each function type, but i only needed it for one but with multi classes, so this worked great for my Cmd pipeline.
Also note, that I just moved around some stuff, and made my own changes.
