The decoder checks +the consistency of the compressed data, so the library should never +crash even in case of corrupted input. +.LP +All functions of the compression library are documented in the file +.IR zlib.h. +The distribution source includes examples of use of the library +the files +.I example.c +and +.IR minigzip.c . +.LP +A Java implementation of +.IR zlib +is available in the Java Development Kit 1.1 +.IP +http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html +.LP +A Perl interface to +.IR zlib , +written by Paul Marquess (pmarquess@bfsec.bt.co.uk) +is available at CPAN (Comprehensive Perl Archive Network) sites, +such as: +.IP +ftp://ftp.cis.ufl.edu/pub/perl/CPAN/modules/by-module/Compress/Compress-Zlib* +.LP +A Python interface to +.IR zlib +written by A.M.
