Author: turkanis
Date: 2008-02-18 00:07:03 EST (Mon, 18 Feb 2008)
New Revision: 43298
URL: http://svn.boost.org/trac/boost/changeset/43298
Log:
overhaul of category_of and close(): stringstream is now dual_seekable, standard file streams and string streams are closable; public streams and streambufs are closable; close() pops filtering streams and streambufs
