1This directory contains examples of the use of zlib and other relevant
2programs and documentation.
3
4enough.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
9fitblk.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
13gun.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
20gzappend.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
25gzjoin.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
30gzlog.c
31gzlog.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
37zlib_how.html
38    painfully comprehensive description of zpipe.c (see below)
39    - describes in excruciating detail the use of deflate() and inflate()
40
41zpipe.c
42    reads and writes zlib streams from stdin to stdout
43    - illustrates the proper use of deflate() and inflate()
44    - deeply commented in zlib_how.html (see above)
45
46zran.c
47    index a zlib or gzip stream and randomly access it
48    - illustrates the use of Z_BLOCK, inflatePrime(), and
49      inflateSetDictionary() to provide random access
