[Boost-users] [iostreams] writing to filtering_ostream

Hello, I've got an application that originally used IOStreams of Boost 1.34. Now I recompiled it with 1.41, and everything stopped functioning. Meanwhile, I figured out that one of the failures occurs due to the following line: iostreams::copy(istream(&someStreambuf), someFilteringStream); The intention was just to copy a chunk of binary data from an input stream to a filtering stream, but it turns out that iostreams::copy() now *closes* the sink. I tried to re-write it like this: someFilteringStream->write(sourceData, sourceSize); or this: iostreams::write(someFilteringStream, sourceData, sourceSize); But neither of the above executes the filter. So what's the right way to do this in 1.41? Thanks.
