| 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 |
| 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 (libz.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 0.94 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). |
