Thank you for this update. A great introduction to the library can be found in the following PowerPoint presentation: https://svn.boost.org/svn/boost/sandbox/shifted_ptr/libs/smart_ptr/doc/Shift...
Thanks.
BTW I haven't corrected the presentation yet but there the disadvantages of a smart pointer list slowness. It was something basically copied from a garbage collection list of disadvantages; I forgot removing the bullet.
I would say one of the disadvantages of manual/smart ptr memory management is slowness. GC, OTOH is fast. To qoute Herb Sutter: "The only thing making .net run faster is GC".
Another question: is it possible to say
shifted_ptr<T> ptr = make_shifted<T>(...)
instead (to enhance exception-safety)?
Yes just by adding some wrapper but I think the reason I did it this way was because 'operator new' can take advantage of a user defined allocator.
Maybe so, but you can either provide both or add make_shifted_alloc<T>( a, ... )
Furthermore I am looking forward testing shifted_ptr on Mozilla Firefox...
Please do tells us what you observe. Is Firefox using shared_ptr already, or?
No but I see memory leaks and a huge consumption of memory ;)
Oh, yes, I have actually moved away from FF because of this. -Thorsten
