pointers to functions problem

Kinda urological for my right now why this isn`t working.

Code:

#include <iostream>

using namespace std;

void myFunction(void *CallThis, int a);
void myCallback();
int main();

void myFunction(void *CallThis, int a) {
	cout << __FUNCDNAME__ << endl;
	cout << CallThis << endl;
	CallThis(); //compile error: error C2064: term does not evaluate to a function taking 0 arguments

}

void myCallback() {
	cout << __FUNCDNAME__ << endl;
}

int main()
{
	void (*ptr)();
	ptr = myCallback;

	ptr(); //working

	myFunction(ptr, 2);

	return EXIT_SUCCESS;
}

I believe your function should be:

Code:

void myFunction(void (*CallThis)(), int a);

A void* is not a function pointer.

Well you got the type wrong in the function call.

Say
void myFunction( void (*CallThis)(), int a)

Also doesn`t work.

Thanks for the ultra informative feedback.

However, this works for me, so I've no idea how you cocked it up.

Code:

#include <iostream>

using namespace std;

#define __FUNCDNAME__ __func__

void myFunction(void (*CallThis)(), int a);
void myCallback();
int main();

void myFunction(void (*CallThis)(), int a) {
	cout << __FUNCDNAME__ << endl;
	cout << CallThis << endl;
	CallThis(); 
}

void myCallback() {
	cout << __FUNCDNAME__ << endl;
}

int main()
{
	void (*ptr)();
	ptr = myCallback;

	ptr(); //working

	myFunction(ptr, 2);

	return EXIT_SUCCESS;
}

$ g++ foo.cpp
$ ./a.exe
myCallback
myFunction
1
myCallback

Sorry.

No idea what I have messed up.

Thanks, working fine now.
