Hi,

on my previous posting I have another questing:

I create my compression stream with

        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;
         }

For a single file I push it to zip with:

l_deflate.push( bio::file_source(p_str1, BOOST_IOS::binary) );

I need a concatination for two files like:
l_deflate.push( bio::file_source(p_str1, BOOST_IOS::binary) );
l_deflate.push( bio::file_source(p_str2, BOOST_IOS::binary) );

for unix shell I do this with:

cat file1.txt > tozip.txt
cat file2.txt >> tozip.txt

How I can push a concatinated file to the deflate stream buffer?

Thanks

Phil
