+ − 1 zlib 0.92 is a beta version of a general purpose compression library.
+ − 2
+ − 3 The data format used by the zlib library is described in the
+ − 4 files zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
+ − 5 in ftp.uu.net:/pub/archiving/zip/doc.
+ − 6
+ − 7 All functions of the compression library are documented in the file
+ − 8 zlib.h. A usage example of the library is given in the file example.c
+ − 9 which also tests that the library is working correctly.
+ − 10
+ − 11 To compile all files and run the test program, just type: make test
+ − 12 (For MSDOS, use one of the special makefiles such as Makefile.msc.)
+ − 13 To install the zlib library (libgz.a) in /usr/local/lib, type: make install
+ − 14 To install in a different directory, use for example: make install prefix=$HOME
+ − 15 This will install in $HOME/lib instead of /usr/local/lib.
+ − 16
+ − 17 The changes made in version 0.92 are documented in the file ChangeLog.
+ − 18 The main changes since 0.9 are:
+ − 19 - don't assume that char is signed (problem on SGI)
+ − 20 - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
+ − 21 - Document the memory requirements in zconf.h
+ − 22 - added "make install"
+ − 23 - added support for DJGPP and Pyramid
+ − 24 - fix an inflate bug for stored blocks.
+ − 25 - various speedups
+ − 26
+ − 27 On MSDOS, this version works in both large and small model. However
+ − 28 small model compression works only for small values of MAX_MEM_LEVEL
+ − 29 and MAX_WBITS (see zconf.h). Small model decompression should work up
+ − 30 to MAX_WBITS=15. This version of zlib does not support small or
+ − 31 medium model with far allocation of big objects.
