Successful Call to NCWNewColorWorld

Q: Can I assume that the value of the ColorSync CMWorldRef parameter returned by the NCWNewColorWorld routine isn't null if the routine was successful? I'd like to determine whether a color world exists before trying to use it.

A: You can assume that if no error is returned, the CMWorldRef parameter will be valid.
