Windows Process Description:

The zlib general purpose data compression/decompression library has the zlib1.dll module as its component. The file zlib1.dll is the official build of zlib as a DLL. It is designed to be a free, general-purpose, lossless data compression library for use on virtually any computer hardware or operating system.

The zlib was written by Jean-loup Gailly (compression) and Mark Adler (decompression). The zlib data format is itself portable across platforms and zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.

Applications that link to the zlib1.dll module can rely on the following specification:

* The exported symbols are exclusively defined in the source files "zlib.h" and "zlib.def". These files are found in the official zlib source distribution.

* The symbols are exported by name and not by ordinal.

* The exported names are undecorated.

* The calling convention of functions is "C" (CDECL).

* The zlib1.dll binary is linked to msvcrt.dll.

If an application uses the zlib1.dll module, linking to the msvcrt.dll module is not required but it is recommended to link your application to msvcrt.dll if it uses the zlib1.dll module. The executables that are involved in the same process and are using the C run-time library, must link to the same library.

There are several libraries in the Win32 system: crtdll.dll, msvcrt.dll, the static C libraries, etc. Since the zlib1.dll module is linked to msvcrt.dll, the executables that depend on it should also be linked to msvcrt.dll.
