For example: On one hand, these macros are kind of nice, because they do the function pointer casting for the user. On the other hand, they hide the field names, which hurts readability a bit. For example, it would be easy to accidentally assign the wrong callback function. Also, it's unfortunate that these macros are needed in the first place. What if we just change new_addr (and old_addr) to be 'void *'? Then the macros wouldn't be as useful, and we could just get rid of them. -- Josh
