    Ok. Let's assume

    int *buffer;

    just for this example.

    ((char *) buffer)++;

    increments buffer by 1, while

    buffer += sizeof(char);

    increments buffer by 4, because an int* is always
    increased/decreased by multiples of sizeof(int).


    buffer += 2;

    would increment the pointer by 8.

    Similarly for other pointer types.
