Re: Is it possible to compare references ?
I don't think that even ANSI C offers intelligent comparison of structs. As Xander said, you should be able to accomplish this by writing a function similar to equalsTo() in Java. Compare the structs member by member:
I don't know how you plan on determining the size of the Point array, so I just threw in a parameter.
