gc_heap* gc_sweep_fixed_size ( gc_heap *  h, int  heap_type, gc_thread_data *  thd  ) Sweep portion of the GC algorithm. Parameters h Heap to sweep heap_type Type of heap, based on object sizes allocated on it thd Thread data object for the mutator using this heap Returns Return the size of the largest object freed, in bytes This portion of the major GC algorithm is responsible for returning unused memory slots to the heap. It is only called by the collector thread after the heap has been traced to identify live objects.
