This directory contains examples of the use of zlib and other relevant |
|
2
|
programs and documentation. |

3
|
|
|
4
|
enough.c |
|
5
|
calculation and justification of ENOUGH parameter in inftrees.h |
|
6
|
- calculates the maximum table space used in inflate tree |
|
7
|
construction over all possible Huffman codes |
|
8
|
|
|
9
|
fitblk.c |
|
10
|
compress just enough input to nearly fill a requested output size |
|
11
|
- zlib isn't designed to do this, but fitblk does it anyway |
|
12
|
|
|
13
|
gun.c |
|
14
|
uncompress a gzip file |
|
15
|
- illustrates the use of inflateBack() for high speed file-to-file |
|
16
|
decompression using call-back functions |
|
17
|
- is approximately twice as fast as gzip -d |
|
18
|
- also provides Unix uncompress functionality, again twice as fast |
|
19
|
|
|
20
|
gzappend.c |
|
21
|
append to a gzip file |
|
22
|
- illustrates the use of the Z_BLOCK flush parameter for inflate() |
|
23
|
- illustrates the use of deflatePrime() to start at any bit |
|
24
|
|
|
25
|
gzjoin.c |
|
26
|
join gzip files without recalculating the crc or recompressing |
|
27
|
- illustrates the use of the Z_BLOCK flush parameter for inflate() |
|
28
|
- illustrates the use of crc32_combine() |
|
29
|
|
|
30
|
gzlog.c |
|
31
|
gzlog.h |
|
32
|
efficiently and robustly maintain a message log file in gzip format |
|
33
|
- illustrates use of raw deflate, Z_PARTIAL_FLUSH, deflatePrime(), |
|
34
|
and deflateSetDictionary() |
|
35
|
- illustrates use of a gzip header extra field |
|
36
|
|
|
37
|
gznorm.c |
|
38
|
normalize a gzip file by combining members into a single member |
|
39
|
- demonstrates how to concatenate deflate streams using Z_BLOCK |
|
40
|
|
|
41
|
zlib_how.html |
|
42
|
painfully comprehensive description of zpipe.c (see below) |
|
43
|
- describes in excruciating detail the use of deflate() and inflate() |
|
44
|
|
|
45
|
zpipe.c |
|
46
|
reads and writes zlib streams from stdin to stdout |
|
47
|
- illustrates the proper use of deflate() and inflate() |
|
48
|
- deeply commented in zlib_how.html (see above) |
|
49
|
|
|
50
|
zran.c |
|
51
|
zran.h |
|
52
|
index a zlib or gzip stream and randomly access it |
|
53
|
- illustrates the use of Z_BLOCK, inflatePrime(), and |
|
54
|
inflateSetDictionary() to provide random access |
|
