I am interested in writing an application which uses zip archives.
Apple includes libgzip in OS X. You can use the gzip API in a Cocoa
app, just like you would in any C app.
Isn't that libz? I've never heard of libgzip, and there isn't one
on my
Mine either that I can find. There is...
man zlib
It can do the lower-level
compression, and it can read and write GZIP files, but it doesn't do
ZIP.
Also in the zip.h included in the zlib folder I have with some gcc
source from sometime there is

/* zip.h -- IO for compress .zip files using zlib

This unzip package allow creates .ZIP file, compatible with PKZip
2.04g
WinZip, InfoZip tools and compatible.
Encryption and multi volume ZipFile (span) are not supported.
Old compressions used by old PKZip 1.x are not supported

Suggests some file format handling. Although searching on PK for the
PK## headers didn't immediately make it clear to me where this
support is.
