Is there some magic required to obtain a "zlib sync flush" when using boost::iostreams::zlib_compressor ?
This is currently a feature request. In the ticket comments, the library author refers to a mailing list thread wherein he does reply with how the library works now:
Thanks that's useful info. The fundamental problem seems to be that the symmetric_filter that zlib_compressor inherits from isn't itself flushable (which seems rather an oversight). Any idea what it would take to add flushable ? On the face of it, it might be as simple as adding the flushable_tag and exposing the existing private flush methods. Or is there much more to it than that ? (I want to give it try at some point). Tim
