[Boost-users] Re: why doesn't scoped_ptr have a custom

Thanks for your reply...

You're right, "reset" would delete the pointer... but when you're getting 
rid of a pointer obtained from a factory, like I was in my case, pointers 
don't always get disposed of using delete, but rather another function (like 
p->release())

And rather than writing special purpose smart pointers for each type of 
deleting function (p->dispose(), p->release(), api_function_free(p), etc..) 
you can use shared_ptr with a custom deleter (here: 
mem_fn(&pointer_type::dispose) or bind(&api_function_free, _1))
