[sldev] Why won't isAvatar() work?

[Michael Miller]

Jason,My apologies, but I am unable to understand fully what you mean. I
understand that a pointer may be pointing to nothing(but even if(&objectp &&
objectp->isAvatar()) doesn't work). How would I make use of an LLPointer?
Would this really help?

Thanks,
Mike
