This directory contains examples of the use of zlib and other relevant
|
|
programs and documentation.
|
|
|
|
enough.c
|
|
calculation and justification of ENOUGH parameter in inftrees.h
|
|
- calculates the maximum table space used in inflate tree
|
|
construction over all possible Huffman codes
|
|
|
|
fitblk.c
|
|
compress just enough input to nearly fill a requested output size
|
|
- zlib isn't designed to do this, but fitblk does it anyway
|
|
|
|
gun.c
|
|
uncompress a gzip file
|
|
- illustrates the use of inflateBack() for high speed file-to-file
|
|
decompression using call-back functions
|
|
- is approximately twice as fast as gzip -d
|
|
- also provides Unix uncompress functionality, again twice as fast
|
|
|
|
gzappend.c
|
|
append to a gzip file
|
|
- illustrates the use of the Z_BLOCK flush parameter for inflate()
|
|
- illustrates the use of deflatePrime() to start at any bit
|
|
|
|
gzjoin.c
|
|
join gzip files without recalculating the crc or recompressing
|
|
- illustrates the use of the Z_BLOCK flush parameter for inflate()
|
|
- illustrates the use of crc32_combine()
|
|
|
|
gzlog.c
|
|
gzlog.h
|
|
efficiently and robustly maintain a message log file in gzip format
|
|
- illustrates use of raw deflate, Z_PARTIAL_FLUSH, deflatePrime(),
|
|
and deflateSetDictionary()
|
|
- illustrates use of a gzip header extra field
|
|
|
|
zlib_how.html
|
|
painfully comprehensive description of zpipe.c (see below)
|
|
- describes in excruciating detail the use of deflate() and inflate()
|
|
|
|
zpipe.c
|
|
reads and writes zlib streams from stdin to stdout
|
|
- illustrates the proper use of deflate() and inflate()
|
|
- deeply commented in zlib_how.html (see above)
|
|
|
|
zran.c
|
|
index a zlib or gzip stream and randomly access it
|
|
- illustrates the use of Z_BLOCK, inflatePrime(), and
|
|
inflateSetDictionary() to provide random access
|
