Extracting gzip via passive library

I need to extract a large gzip data stream in C ++ (on Linux) into memory. I intended to use libarchive

, but I have a limitation that I cannot block or use any sync.

AFAIR, to use a custom reader libarchive

, it must block until data is available.

So I would like it to be the other way around. A library that has write / execute callbacks and the ability to manually enter data.

Is there any library that does this, or is it quicker to modify libarchive

to work differently?

If you only want gzip unpacking and not tar extraction, you can use zlib . Probably already on your system zlib.h (also has documentation ) and libz.so.



If you also require tar extraction, you can try libtar .
