4695,Exposing packed_iarchive::position(),astukalov@…,Matthias Troyer,"I'm transferring variable number of packed objects (of same datatype) using isend/recv.
''(I'm new to MPI, so I might be wrong -- but is it true that for multiple isends with the same message tag the received message would contain a concatenation?)''

Then I'm reading objects out of the buffer using packed_iarchive. Because their number is not known, I need a way to know if I read all objects from archive. `packed_iprimitive` already has `position` field. 

Is it worth to make `position()` publicly accessible? The patch against trunk is attached.",Feature Requests,closed,Boost 1.46.0,mpi,Boost 1.44.0,Optimization,wontfix,,
