Hi,
I posted here a while ago streambuf adapters. There was no any answer. May
be you might find it intresting.
The main idea is simple: to present any linear sequence as
std::basic_streambuf<>.
Here are the file.

If not, it would be a good idea to have an I/O stream that can have a custom stream buffer, that way you can use stream facilities on these buffers, thus gaining access to compression, encription, etc. [TRUNCATE] I just put several I/O-related items up for review a few months ago. One of the items was a set of stream class templates that wrap a containing stream buffer. Look for stuff like "streambuf_wrapping.hpp". The code as it was reviewed is in the file section of our Yahoo Groups space under the name "more_io.zip". Updated versions of the code exist in the Boost-sandbox CVS.

[boost] RE: Interest in library generating streambufs from objects
Thanks for your interest. I have posted the library at http://groups.yahoo.com/group/boost/files/streambuf_lib/. The implementation needs to be streamlined, but it works, and the main ideas are clear enough.

This is good idea! I had thought about composing streambufs to create new streambufs, and indeed this seems fairly straightforward using my approach (perhaps the most difficult part is selecting suitable names for the composition operations -- how about 'operator+' ?) However, reworking the project in terms of iterator adaptors is a completely different story (I think.) Very interesting! Could you give a more detailed example?
