Anyway, here's my revised snippet that satisfies all my criteria: -- JFB

#include <iostream>

#include

struct ObjectStruct { int refCount ;

ObjectStruct() : refCount(0) { std::cout << std::hex << (int) this << " - I'm born" << std::endl ; }

void refer() { ++refCount ; } void unrefer() { if (--refCount == 0) delete this ; }

virtual ~ObjectStruct() { std::cout << std::hex << (int) this << " - I'm gone" << std::endl ; } } ;

void intrusive_ptr_add_ref(ObjectStruct * p) { p->refer() ; } void intrusive_ptr_release(ObjectStruct * p) { p->unrefer() ; }

Are you going to make it thread-safe (or is that something you just left out of the example?)?
