Short: General purpose data compression library Author: Jean-loup Gailly and Mark Adler Uploader: carsten larsen mail com (Carsten Larsen) Type: dev/lib Version: 1.2.8 Architecture: m68k-amigaos >= 3.0.0 DESCRIPTION This is a port of Jean-loup Gailly and Mark Adlers famous data compression library for development on AmigaOS 3.x ABOUT zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1) and in the GIF image format, the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be re- duced, if necessary, at some cost in compression. A more precise, technical discussion of both points is available on another page. zlib was written by Jean-loup Gailly (compression) and Mark Adler (decompres- sion). Jean-loup is also the primary author/maintainer of gzip(1), the author of the comp.compression FAQ list and the former maintainer of Info-ZIP's Zip; Mark is also the author of gzip's and UnZip's main decompression routines and was the original author of Zip. Not surprisingly, the compression algorithm used in zlib is essentially the same as that in gzip and Zip, namely, the 'deflate' method that originated in PKWARE's PKZIP 2.x. USAGE Included binaries were cross-compiled with an AmigaOS compatible GCC using the following configuration: CHOST=m68k-amigaos CFLAGS="-O3 -noixemul" ./configure Two binaries are supplied for testing: minigzip and example. Be sure to read the source code for minigzip before using it. zlib is needed when building other applications. To use zlib with GCC either copy zlib.a to your library directory and use the switch -lz or compile the source yourself using the desired configuration. A partial list of over 500 applications using zlib is available from the zlib homepage: http://zlib.net/apps.html The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and rfc1952 (gzip format). SECURITY Versions 1.1.4 (March 2002) and later eliminate an earlier potential security vulnerability. Any software that is linked against or derived from an earlier version of zlib should be upgraded immediately.
