Re: [Boost-users] is there limitation on the file size generated byserialization

Note that all archive classes currently included with the serialization
library depend one std::streambuf to do the actual input/output
and hence inherit all the attributes and limitions of the implementation
of streambuf that you're using.

SO...

make a small test program which tests wheter std::fostream
can create a file larger than the size you're interested in.

currently - 1.34 - there is a limit of 2G objects in a collection.

This limitation is being relaxed on 1.35 to handle up to
(2G)**2 on 64 bit machines.

No.  This COULD be done by deriving from one of the
standard archives and adding on alittle bit of extra functionality.
But, if this were my concern I would make a custom streambuf
to do the job and use it with my archive.
