OfxPropertySetHandle — Blind data type used to hold sets of properties
#include "ofxCore.h" typedef struct OfxPropertySetStruct *OfxPropertySetHandle;
Properties are not accessed on their own, nor do they exist on their own. They are grouped and manipulated via an OfxPropertySetHandle.
Any object that has properties can be made to return it's property set handle via some call on the relevant suite. Individual properties are then manipulated with the property suite through that handle.
