| 1 | ZLIB DATA COMPRESSION LIBRARY
|
|---|
| 2 |
|
|---|
| 3 | zlib 1.2.11 is a general purpose data compression library. All the code is
|
|---|
| 4 | thread safe. The data format used by the zlib library is described by RFCs
|
|---|
| 5 | (Request for Comments) 1950 to 1952 in the files
|
|---|
| 6 | http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
|
|---|
| 7 | and rfc1952.txt (gzip format).
|
|---|
| 8 |
|
|---|
| 9 | All functions of the compression library are documented in the file zlib.h
|
|---|
| 10 | (volunteer to write man pages welcome, contact [email protected]). Two compiled
|
|---|
| 11 | examples are distributed in this package, example and minigzip. The example_d
|
|---|
| 12 | and minigzip_d flavors validate that the zlib1.dll file is working correctly.
|
|---|

| 14 | Questions about zlib should be sent to <[email protected]>. The zlib home page
|
|---|
| 15 | is http://zlib.net/ . Before reporting a problem, please check this site to
|
|---|
| 16 | verify that you have the latest version of zlib; otherwise get the latest
|
|---|
| 17 | version and check whether the problem still exists or not.
|
|---|
| 18 |
|
|---|
| 19 | PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
|

| 38 | minigzip.exe A statically-bound test program (using zlib.lib, not the dll)
|
|---|
| 39 | minigzip.pdb Symbolic information for debugging minigzip.exe
|

| 40 |
|
|---|
| 41 | minigzip_d.exe A zlib1.dll bound test program (using zdll.lib)
|
|---|
| 42 | minigzip_d.pdb Symbolic information for debugging minigzip_d.exe
|
|---|
| 43 |
|
|---|
| 44 | zlib.h Install these files into the compilers' INCLUDE path to
|
|---|
| 45 | zconf.h compile programs which use zlib.lib or zdll.lib
|
|---|
| 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
|
|---|
| 49 |
|
|---|
| 50 | zlib.lib Install these files into the compilers' LIB path to link zlib
|
|---|
| 51 | zlib.pdb into compiled programs, without zlib1.dll runtime dependency
|
|---|
| 52 | (zlib.pdb provides debugging info to the compile time linker)
|
|---|
| 53 |
|
|---|
| 54 | zlib1.dll Install this binary shared library into the system PATH, or
|
|---|
| 55 | the program's runtime directory (where the .exe resides)
|
|---|
| 56 | zlib1.pdb Install in the same directory as zlib1.dll, in order to debug
|
|---|
| 57 | an application crash using WinDbg or similar tools.
|
|---|
| 58 |
|
|---|
| 59 | All .pdb files above are entirely optional, but are very useful to a developer
|
|---|
| 60 | attempting to diagnose program misbehavior or a crash. Many additional
|
|---|
| 61 | important files for developers can be found in the zlib127.zip source package
|
|---|
| 62 | available from http://zlib.net/ - review that package's README file for details.
