Yes. I use zlib extensively in my application, which runs on
10.4 and 10.5.

No. The library will return Z_VERSION_ERROR if you try to
inflate something that the working zlib library doesn't understand.

That said, zlib has been stable for years. If you're just now
getting started with compression, you should't have version
problems (that you can't manage).

>Any endian issues with zlib?


zlib compresses bytes, not words, so there are no inherent
endian issues when using zlib. Your actual data is another
matter; You'll have the same endian issues you would
storing/moving uncompressed data between systems.
