Casting Pointers to Functions

Hey guys,

Today's class seemed a little confusing to some.

Basically what he was saying is when your casting just take the type and put that in front of the pointer. Here's a simple example...

double example1(int, int, double);

int main()
{
/* Create pointer to a void type */
void (*p);
double holder = 0;
/*Cast pointer of void type to function type wanted */
p = (*(double (*)(int, int, double))p);
/*Let pointer be pointed to function start */
p = example1;
/*Run pointer and hold returned value */
holder = *p(2, 4, 5);



}
