Hi,

I have implemented this litte code to compress a file

bio::filtering_streambuf< bio::input > l_deflate;
switch (m_compress) {
     case gzip   : l_deflate.push( bio::gzip_compressor() );     break;
     case bzip2  : l_deflate.push( bio::bzip2_compressor() );    break;
}

l_deflate.push( bio::file_source(p_str, BOOST_IOS::binary) );

I need only the number of compressed bytes of l_deflate. I try to
use l_deflate.size() but it returns only a fixed number.

How I can read the number of compressed bytes?

Thanks

Phil
