hi all, i was wondering if there are any formal initiatives in the boost community to provide 'lock free' data structures using CAS (compare and swap)? in particular, this looks promising... "Instead of providing a separate atomic smart pointer, we propose additions to shared_ptr's interface to address this use case. A typical example scenario — a "lock-free" reader/writer pattern — that takes advantage of this functionality is outlined below:..." [http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2007/n2297.html#atomic] is this likely to happen this year? i've seen some other discussion, such as http://www.nabble.com/Lock-free-atomic_shared_ptr%3CT%3E--td14958758.html i've used the Microsoft interlocked API's in a past (audio processing) project, but i'm developing a video pipeline for Linux/Win32 and it would be a huge 'boost' to be able to eliminate some locking and have deterministic real time. if that were introduced via the shared_ptr interface, i'd be over the moon. unfortunately, i don't have the skills to really contribute to this initiative, but i wld like to add my voice to those who might find a use for it! cheers, jono
