Actually, this is an interesting thought. I have the need for managing a dynamic array of roots but this could be handled just as easily by tracking a variable pointing to a Squeak array.

A variable in C is more-or-less a one-place array, so perhaps supporting arrays is the simpler option?

Turns out not. The code is much simpler supporting just individual oop locations (variables) so I decided to go with the following interface:

sqInt oopVar; /* declare a global that we wish to track */

{ ... oopVar = vm->nilObject(); /* don't forget to initialize it !!! */ vm->addGCRoot(&oopVar); /* update it */ ... }

and to undo that

{ ... vm->removeGCRoot(&oopVar); ... }
