2UnZip 0.15 additionnal library
3
4
5 This unzip package allow extract file from .ZIP file, compatible with
6PKZip 2.04g, WinZip, InfoZip tools and compatible.
7
8 Multi volume ZipFile (span) are not supported, and old compression used by old
9PKZip 1.x are not supported.
10
11See probdesc.zip from PKWare for specification of .ZIP format.
12
13What is Unzip
14 The Zlib library support the deflate compression and the creation of gzip (.gz)
15file. Zlib is free and small.
16 The .Zip format, which can contain several compressed files (.gz can containt
17only one file) is a very popular format. This is why I've written a package for reading file compressed in Zipfile.
18
19Using Unzip package
20
21You need source of Zlib (get zlib111.zip and read zlib.h).
22Get unzlb015.zip and read unzip.h (whith documentation of unzip functions)
23
24The Unzip package is only two file : unzip.h and unzip.c. But it use the Zlib
25 files.
26unztst.c is a simple sample program, which list file in a zipfile and display
27 README.TXT or FILE_ID.DIZ (if these files are found).
28miniunz.c is a mini unzip program.
29
30I'm also currenlyt writing a zipping portion (zip.h, zip.c and test with minizip.c)
31
32Please email me for feedback.
33I hope my source is compatible with Unix system, but I need your help for be sure
