I missed this from the original post. So that explains the myPtr part
of it. So you want to sort the pointers based on their address value?
The code isn't going to very different from the same code for
integers:

void bubbleSort(void** array, size_t length)
{
    size_t i, j;
    for (i = length - 1; i > 0; --i) {
        for (j = 0, j < i, ++j) {
            if (array[j] > array[j+1]) {
                void* temp = array[j];
                array[j] = array [j+1];
                array[j+1] = temp;
            }
        }
    }
}

Really, if you replace all occurences of "void*" with "int", it's
exactly like sorting integers.
