Invoke the specified `accessor` on the (non‐modifiable) selection of the specified `object`, supplying `accessor` with the corresponding selection information structure. The supplied `accessor` must be a callable type that can be called as if it had the following signature: ` template <class t_INFO> int accessor(const SELECTION_TYPE& selection, const t_INFO& info); ` Return the value returned from the invocation of `accessor`. The behavior is undefined unless `k_UNDEFINED_SELECTION_ID != selectionId(object)`.
