Swapping pointers in C (char, int)

Question

I have been struggling to understand the different behaviour when swapping pointers in C. If I want to swap two int pointers, then I can do

void

If you have the luxury of working in C++, use this:

template
void swapPrimitives(T& a, T& b)
{
    T c = a;
    a = b;
    b = c;
}

Granted, in the case of char*, it would only swap the pointers themselves, not the data they point to, but in most cases, that is OK, right?
