1 ZLIB DATA COMPRESSION LIBRARY
|
cannam@128
|
2
|
cannam@128
|
3 zlib 1.2.8 is a general purpose data compression library. All the code is
|
cannam@128
|
4 thread safe. The data format used by the zlib library is described by RFCs
|
cannam@128
|
5 (Request for Comments) 1950 to 1952 in the files
|
cannam@128
|
6 http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
|
cannam@128
|
7 and rfc1952.txt (gzip format).
|
cannam@128
|
8
|
cannam@128
|
9 All functions of the compression library are documented in the file zlib.h
|
cannam@128
|
10 (volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled
|
cannam@128
|
11 examples are distributed in this package, example and minigzip. The example_d
|
cannam@128
|
12 and minigzip_d flavors validate that the zlib1.dll file is working correctly.

|
cannam@128
|
16 verify that you have the latest version of zlib; otherwise get the latest
|
cannam@128
|
17 version and check whether the problem still exists or not.

45 zconf.h compile programs which use zlib.lib or zdll.lib
|
cannam@128
|
46

47 zdll.lib Install these files into the compilers' LIB path if linking

48 zdll.exp a compiled program to the zlib1.dll binary
|
cannam@128
|
49
|
cannam@128

50 zlib.lib Install these files into the compilers' LIB path to link zlib

cannam@128
|
51 zlib.pdb into compiled programs, without zlib1.dll runtime dependency
|
cannam@128
|
52 (zlib.pdb provides debugging info to the compile time linker)

54 zlib1.dll Install this binary shared library into the system PATH, or

55 the program's runtime directory (where the .exe resides)
|
cannam@128
|
56 zlib1.pdb Install in the same directory as zlib1.dll, in order to debug

cannam@128
|
57 an application crash using WinDbg or similar tools.

|
cannam@128
|
59 All .pdb files above are entirely optional, but are very useful to a developer

cannam@128
|
60 attempting to diagnose program misbehavior or a crash. Many additional
|
cannam@128
|
61 important files for developers can be found in the zlib127.zip source package
|
cannam@128
|
62 available from http://zlib.net/ - review that package's README file for details.
