NAME
zlib - compression/decompression library
SYNOPSIS
[see zlib.h for full description]
DESCRIPTION
The libz library is a general purpose data compression library. The
code is thread safe, assuming that the standard library functions used
are thread safe, such as memory allocation routines. It provides in-
memory compression and decompression functions, including integrity
checks of the uncompressed data. This version of the library supports
only one compression method (deflation) but other algorithms may be
added later with the same stream interface.
Compression can be done in a single step if the buffers are large
enough or can be done by repeated calls of the compression function.
In the latter case, the application must provide more input and/or con‐
sume the output (providing more output space) before each call.
The library also supports reading and writing files in gzip(1) (.gz)
format with an interface similar to that of stdio.
The library does not install any signal handler. The decoder checks
the consistency of the compressed data, so the library should never
crash even in the case of corrupted input.
All functions of the compression library are documented in the file
zlib.h. The distribution source includes examples of use of the li‐
brary in the files test/example.c and test/minigzip.c, as well as other
examples in the examples/ directory.
Changes to this version are documented in the file ChangeLog that ac‐
companies the source.
zlib is built in to many languages and operating systems, including but
not limited to Java, Python, .NET, PHP, Perl, Ruby, Swift, and Go.
An experimental package to read and write files in the .zip format,
written on top of zlib by Gilles Vollant (info@winimage.com), is avail‐
able at:
http://www.winimage.com/zLibDll/minizip.html and also in the
contrib/minizip directory of the main zlib source distribution.

The data format used by the zlib library is described by RFC (Request
for Comments) 1950 to 1952 in the files:
http://tools.ietf.org/html/rfc1950 (for the zlib header and
trailer format)
http://tools.ietf.org/html/rfc1951 (for the deflate compressed
data format)
http://tools.ietf.org/html/rfc1952 (for the gzip header and
trailer format)

REPORTING PROBLEMS
Before reporting a problem, please check the zlib web site to verify
that you have the latest version of zlib; otherwise, obtain the latest
version and see if the problem still exists. Please read the zlib FAQ
at:
