DestroyMagicWand is prototyped to return a MagickWand. This seemed pretty circular to me until I realized it actually returns the value 0. But this still left the question, why not prototype it as a void? Does this have some rationale?

(Same with other Destroy functions)

In security programming you are encouraged to reset any variable when you are finished using it. Its a convenience then to use

• wand = DestroyWand(wand);
