.TH ZLIB 3 "29 Jan 2012"
|
|
.SH NAME
|
|
zlib \- compression/decompression library
|
|
.SH SYNOPSIS
|
|
[see
|
|
.I zlib.h
|
|
for full description]
|
|
.SH DESCRIPTION
|
|
The
|
|
.I zlib
|
|
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.
|
|
.LP
|
|
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 consume the output
|
|
(providing more output space) before each call.
|
|
.LP
|
|
The library also supports reading and writing files in
|
|
.IR gzip (1)
|
|
(.gz) format
|
|
with an interface similar to that of stdio.
|
|
.LP
|
|
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.
|
|
.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
|
|
in the files
|
|
.I test/example.c
|
|
and
|
|
.IR test/minigzip.c,
|
|
as well as other examples in the
|
|
.IR examples/
|
|
directory.
|
|
.LP
|
|
Changes to this version are documented in the file
|
|
.I ChangeLog
|
|
that accompanies the source.
