H A DFAQ2 Frequently Asked Questions about zlib
5 If your question is not there, please check the zlib home page
6 https://zlib.net/ which may have more recent information.
7 The latest zlib FAQ is at https://zlib.net/zlib_faq.html
10 1. Is zlib Y2K-compliant?
12 Yes. zlib doesn't handle dates.
16 The zlib sources can be compiled without change to produce a DLL. See the
17 file win32/DLL_FAQ.txt in the zlib distribution.
19 3. Where can I get a Visual Basic interface to zlib?

8 To build the zstd wrapper for zlib the following files are required:
9 - zlib.h
10 - a static or dynamic zlib library
17 The first two files are required by all projects using zlib and they are not included with the zstd…
23 Let's assume that your project that uses zlib is compiled with:
27 - change all references with `#include "zlib.h"` to `#include "zstd_zlibwrapper.h"`
37 Your project should work as before with zlib. There are two options to enable zstd compression:
