1 .TH ZLIB 3 "2 May 2012" | |
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, assuming that the standard library functions | |
13 used are thread safe, such as memory allocation routines. | |
14 It provides in-memory compression and decompression functions, | |
15 including integrity checks of the uncompressed data. | |
16 This version of the library supports only one compression method (deflation) | |
17 but other algorithms may be added later | |
18 with the same stream interface. | |
19 .LP | |
20 Compression can be done in a single step if the buffers are large enough | |
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 the 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 test/example.c | |
40 and | |
41 .IR test/minigzip.c, | |
42 as well as other examples in the | |
43 .IR examples/ | |
44 directory. | |
45 .LP | |

47 .I ChangeLog | |
48 that accompanies the source. | |
