[hoc-users] detecting nil?

[David C. <dw...@dw...>]

Hola!

How would one go about detecting a nil result in a Cocoa call (as =20
opposed to NSNull)?I.e., if you have an NSEnumerator and you are =20
trying to retrieve objects progressively, the end is indicated by =20
nil.  I could not find anything on google about how to detect this=97is =20=

this documented?  (It would seem like there would have to be some =20
sort of coercion at a lower level, possibly exported as some function =20=

(i.e., `nil')).

Thanks,

David Christensen=
