Hi,

I successfully create squirrel objects from C.

However, because they contain references to reference counted C++ objects (which I have bound to squirrel using Sqrat), there is a point at which I need to destroy the squirrel objects (this allowing their referenced C++ objects to die).

I tried using sq_deleteslot to delete the reference to the object from the root, but this doesn't seem to be having the desired effect.

as an illustration

Code:

class ViewHandler
{
    constructor(view)  // view is a reference to a Reference counted C++ class CView
    {
         view_ = view; // view can't die until this reference is removed
    }

    view_ = null;
}

You can't manually delete Squirrel objects; they'll only be destroyed when the last reference to them goes away (or some time later, if you enabled the garbage collector)

You could effectively kill the C++ object by setting its pointers to NULL, but you'd need to do a null check every time you use it, and throw a Squirrel exception with sq_throwerror.
