1 .TH ZLIB 3 "18 July 2005"
2 .SH NAME
3 zlib \- compression/decompression library
4 .SH SYNOPSIS
5 [see
6 .I zlib.h
7 for full description]
8 .SH DESCRIPTION
9 The
10 .I zlib
11 library is a general purpose data compression library.
12 The code is thread safe.
13 It provides in-memory compression and decompression functions,
14 including integrity checks of the uncompressed data.
15 This version of the library supports only one compression method (deflation)
16 but other algorithms will be added later
17 and will have the same stream interface.
18 .LP
19 Compression can be done in a single step if the buffers are large enough
20 (for example if an input file is mmap'ed),
21 or can be done by repeated calls of the compression function.
22 In the latter case,
23 the application must provide more input and/or consume the output
24 (providing more output space) before each call.
25 .LP
26 The library also supports reading and writing files in
27 .IR gzip (1)
28 (.gz) format
29 with an interface similar to that of stdio.
30 .LP
31 The library does not install any signal handler.
32 The decoder checks the consistency of the compressed data,
33 so the library should never crash even in case of corrupted input.
34 .LP
35 All functions of the compression library are documented in the file
36 .IR zlib.h .
37 The distribution source includes examples of use of the library
38 in the files
39 .I example.c
40 and
41 .IR minigzip.c .
42 .LP
43 Changes to this version are documented in the file
44 .I ChangeLog
45 that accompanies the source,
46 and are concerned primarily with bug fixes and portability enhancements.
