zlib 0.8 is a beta version of a general purpose compression library.
|
|
This is the first version with no known bugs. (There may still be
|
|
problem on SGI, to be checked.)
|
|
|
|
The data format used by the zlib library is described in the
|
|
file zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
|
|
in ftp.uu.net:/pub/archiving/zip/doc.
|
|
|
|
All functions of the compression library are documented in the file
|
|
zlib.h. A usage example of the library is given in the file example.c
|
|
which also tests that the library is working correctly.
|
|
To compile all files and run the test program, just type: make test
|
|
|
|
The changes made in version 0.8 are documented in the file ChangeLog.
|
|
The main changes since 0.71 are:
|
|
- added fast inflate (inffast.c)
|
|
- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
|
|
is incompatible with previous versions of zlib which returned Z_OK.
|
|
- work around a nasty TurboC compiler bug
|
|
|
|
On MSDOS, this version works in both large and small model. However
|
|
small model compression works only for small values of MEM_LEVEL and
|
|
WBITS (see zutil.h). Small model decompression should work up to WBITS=15.
|
|
This version of zlib does not yet support small or medium model with
|
|
far allocation of big objects.
