I am stepping through interprocess shared memory code and I was a little confused by the offset_ptr code that I was hitting. I cannot figure out how that is specified to the template of rbtree_best_fit. I see in boost/interprocess/interprocess_fwd.hpp declaring managed_shared_memory by typedef'ing basic_managed_shared_memory with rbtree_best_fit<mutex_family> as the AllocationAlgorithm argument but I can't figure out how offset_ptr is is supplied as the VoidPointer argument to the rbtree_best_fit template. That template has 3 arguments but the forward declaration only provides one. Are the other two somehow inferred? If so, how?
There is a predeclaration for rbtree_best_fit in interprocess_fwd.hpp specifying default arguments ////////////////////////////////////////////////// // Memory allocation algorithms ////////////////////////////////////////////////// //... template<class MutexFamily, class VoidMutex = offset_ptr<void>, std::size_t MemAlignment = 0> class rbtree_best_fit; Best, Ion
