zlib && zip files

Hi,
I need to decompress zip archive. I wrote a parser of zip file, i obtain
the compressed data, but when i call zlib.decompress (data) on them,
it throws this error:

decbuf = decompressor.de compress(compre ssed_data)

error: Error -3 while decompressing: unknown compression method

I try to compress by zlib the same data which are in that file, the
result was 6 bytes bigger, '\x78\xda' on begin and '\xc9\x1f\x87\x 0b' on end
when i tried to put this extending data to zlib decompressor, it
decompress some files of zip archive, but it fails, when i try to
decompress 100MB file from archive

could you help, please?
thanks
Honza

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
