- zlib 0.93 is a beta version of a general purpose compression library.
- The data format used by the zlib library is described in the
- files 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
- (For MSDOS, use one of the special makefiles such as Makefile.msc.)
- To install the zlib library (libgz.a) in /usr/local/lib, type: make install
- To install in a different directory, use for example: make install prefix=$HOME
- This will install in $HOME/lib instead of /usr/local/lib.
- The changes made in version 0.93 are documented in the file ChangeLog.
- The main changes since 0.9 are:
- - temporarily disable inline functions
- - make deflate deterministic
- - don't use signed char in inflate (not portable enough)
- - fix inflate memory leak for segmented architectures
- - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
- - Document the memory requirements in zconf.h
- - added "make install"
- - added support for DJGPP and Pyramid
- - fix an inflate bug for stored blocks.
- - various speedups
- On MSDOS, this version works in both large and small model. However
- small model compression works only for small values of MAX_MEM_LEVEL
- and MAX_WBITS (see zconf.h). Small model decompression should work up
- to MAX_WBITS=15. This version of zlib does not support small or
- medium model with far allocation of big objects.
