Subject: [boost] [interprocess] atomic<offset_ptr>

hi ion,

i was wondering, what would be the best way to provide an
atomic<offset_ptr>? it cannot be used out of the box, as offset_ptr does
not conform to the std/boost::atomic<> requirements.
afaict, one would have to pre-compute the offset for a specific memory
location when performing a compare_exchange or store and fix up the
offset after an atomic load. to do that, it will probably be required to
access some internals of the offset_ptr.

also, if i'm going to work on it (not sure if i will have time), where
shall the implementation go? in a way, i'd rather put it into
interprocess than into atomic.

cheers, tim
