Keywords: can you cast them?

The delima - Is it possible to cast a 'pointer to' a function?

What I have is a char * that holds the address of a function.
int	foo();
char	*addr = foo;
Would it be possible to call the function foo() via the variable addr?

Secondly is it possible to have an array of type 'pointer to' function.
i.e. 
int  (*function)()[SIZE];
something like the above, I was able to achieve this using this:
struct	fct {
            int  (*func)();
            } f_array[SIZE];
function()
{
    int x;
    printf("offset: ");
    scanf("%d",&x);
    (*f_array[x].func)();
}
Is there another way???

Something to think about...
Thanx in advance for **ANY** help,
- Tom
