How do I type cast a pointer to void so I can use it in a loop?
void *smMacroPtr;
for(fooPtr = (int *)foo; fooPtr < (int *)(&foo+1); ++fooPtr, ++((int*)(smMacroPtr)))
if (smMacroPtr != fooPtr)
{
cout << *smMacroPtr << " != " << *fooPtr << endl;
break;
}
++((int*)(smMacroPtr)) // this needs to be incremented but compiler still says unknown type. I tried several combinations.

An easy example:
Take notice of:Code:#include <stdio.h> int main (void) { void *counter; for (*(int *) counter = 0; *(int *) counter < 10; (*(int *) counter)++) { printf ("%d\n", *(int *) counter); } return 0; }
(*(int *) counter)++
This means that you're casting the pointer to void to a pointer to int. Since you don't want to increment the pointer, but the variable where the pointer points to, you need that '*' in front of all.
