Why these warnings?

[Sathyaish]

I am practicing function pointers. Here's what I am doing: passing a function pointer to another function. It all goes well except for the two warnings I get:


[list=1][*]'ConsumeFnPointer' : too many actual parameters[*]declared formal parameter list different from definition[/list=1]


I am curious as to why I get those warnings. Can we not pass variable arguments to the right of the function pointer argument? Has it got something to do with the calling sequence (__stdcall, ___pascal etc.)?

Here's the code:

#include <stdio.h>

/*float Add(float, float);
float Subtract(float, float);
float Multiply(float, float);
float Divide(float, float);
float (*ptr)(float, float);
*/

int DoSomething(int, int);
int ConsumeFnPointer(int (*ptr1)(int, int));

int main()
{
	//ptr=&Add;
	//printf("%f",ptr(3,9));
	printf("%d", ConsumeFnPointer(&DoSomething,12,4));

}

/*float Add(float a, float b) { return a+b;}
float Subtract(float a, float b){ return a-b;}
float Multiply(float a, float b){ return a*b;}
float Divide(float a, float b){ return a/b;}
*/

int ConsumeFnPointer(int (*ptr1)(int a, int b), int a, int b)
{
	return (*ptr1)(a,b);
}

int DoSomething(int a, int b)
{
	return 1+a-b;
}

The prototype and the definition of ConsumeFnPointer don't match.

Yup! Thanks! Just saw that a moment after making that post.
