Re: [sc-dev] primitives: divine class of slot

[James McCartney <asynth@xxxxxx>]

There is isKindOfSlot for when you have a slot and you don't know what 
it holds (maybe not an object pointer).

inline bool isKindOfSlot(PyrSlot *slot, struct PyrClass *testclass)


Every object has a field called classptr. See PyrObject.h

struct PyrObjectHdr {
	struct PyrObjectHdr *prev, *next;
	struct PyrClass *classptr;		
...

If you have a slot and you want a class pointer from it you can use

inline struct PyrClass* classOfSlot(PyrSlot *slot)
