What if you don't have a pointer, and instead you only have a reference to the buffer that is being swapped?

If array is 100000 items and it needs to be swapped then you really should have that pointer. :rolleyes:

This won't do anything that you suggested. Why not see your suggestion through to the end? You will see it won't work.

How do you reseat the reference if you change the pointer, as you suggested should be done? Example:

Code:

---

void SwapMe(char &data, int size)
{
}

---

Try to change the address of "data" in the SwapMe function to point to a different buffer. You can't. And also, you didn't address the big issue, and that is your suggestion is not a "heck of a lot faster" than what already has been posted. In fact, it could be a "heck of a lot slower".
