Is there an option, using zlib or boost, to unpack a gzip archive containing several files? All options which I figured out were for 1 single file in archive.
I know about minizip, quazip and other useful libs, but I need to try to find an option without additional libraries.
gzip doesn't compress multiple files. It only compresses one file. The reason you can't find a way to extract gzip archives is that they don't exist.
