zlib 0.94 is a beta version of a general purpose compression library.
|
|
|
|
|
Unless new bugs are found it will be released again as the first official
|
|
|
|
|
version (1.0). This version has no known bugs.

|
The data format used by the zlib library is described in the
|
2011-09-10 10:07:35 +04:00
|
|
|
files zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
|
2011-09-10 09:36:31 +04:00
|
|
|
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
|
|
|
|
|
(For MSDOS, use one of the special makefiles such as Makefile.msc.)
|

|
|
|
To install the zlib library (libz.a) in /usr/local/lib, type: make install
|
|
|
|
|
To install in a different directory, use for example:
|
|
|
|
|
make install prefix=$HOME
|
2011-09-10 10:07:35 +04:00
|
|
|
This will install in $HOME/lib instead of /usr/local/lib.

The changes made in version 0.94 are documented in the file ChangeLog.
|
|
|
|
|
The main changes since 0.93 are:
|
|
|
|
|
- support MSDOS small and medium model
|
|
|
|
|
- fix deflate with flush (could sometimes generate bad output)
|
|
|
|
|
- fix deflateReset (zlib header was incorrectly suppressed)
|
|
|
|
|
- added support for VMS
|
|
|
|
|
- allow a compression level in gzopen()
|
|
|
|
|
- gzflush now calls fflush
|
|
|
|
|
- For deflate with flush, flush even if no more input is provided.
|
|
|
|
|
- rename libgz.a as libz.a
|
|
|
|
|
|
|
|
|
|
For MSDOS, the small and medium models are supported only for Microsoft C.
|
|
|
|
|
(It should be easy to support them for Borland C also, but I don't have
|
|
|
|
|
a recent Borland compiler to test with.) The small model currently works
|
|
|
|
|
for Turbo/Borland C but only with reduced performance to avoid any far
|
|
|
|
|
allocation (tested with -DMAX_WBITS=11 -DDEF_WBITS=11 -DMAX_MEM_LEVEL=3).
