C++ cross-platform zlib simplifer-wrapper

Question

I\'m looking for a wrapper that distills zlib to:

1. OpenZipFile()
2. GetItemInfo(n)
3. UnzipItem(n) // Bonus points for unzipping recursively if ite

Answer 1

firstobject's easy zlib stays cross-platform; it has zlib in a single file easyzlib.c and exposes only ezcompress and ezuncompress functions with the added feature of determining the memory requirement before allocating the exact size.

Answer 2

You could try to grab the code from another FOSS project. ScummVM, for example, has a highly portable Zlib wrapper (implementation, header) with all the functions you need, plus an OO layer for interfacing generically with any other kind of archive.

Maybe that's a good starting point? The wrapper functions are totally standalone and portable (heck, they even work on a Nintendo DS), but the OO layer depends on many custom classes which may be hard to add to your own project.
