GNU adns for Win32

Advanced, easy to use, asynchronous-capable DNS client library and utilities.

adns, originally written for Linux/UNIX by Ian Jackson, is a resolver library for C (and C++) programs. The Win32 version is tested on Windows NT 4.0 SP 6, Windows 98 Second Edition and Windows 2000. The library comes as a dll and as a static library. The intention behind this port is to ease cross platform development of Internet server software.

Please see the adns website for general information about adns.

Current ported version

The latest ported version is 0.8.

Supported compilers

Microsoft Visual C++ 6.0

Note that the library is compiled with code-generation for [Debug] Multithread DLL. If you use different code-generation in your projects, you will most likely get some strange linkage errors.

The shipped runtime library and dll should be compatible with most Win32 compilers. The functions are native C functions.

Win32 specific defines

ADNS_MAP_UNIXAPI to include the following UNIX functions (Note: The functions are mapped to functions that are named adns_*, so you must include adns.h in your project in order to use thhe adns version of the ported unix system calls):
- gettimeofday()
- writev()
- inet_aton()
- getpid()
ADNS_MAP_POLLAPI to include a port of the Linux poll() system call. Se the implementation note above.
ADNS_DLL to use the DLL version of the library.

adns as a dll

The dll comes in two versions,

adns_dll.dll - normal runtime version
adns_dlld.dll - debug version with symbolic information

You must #define ADNS_DLL before including the adns header file if you want to use the dll.

Header file: adns.h
Library: adns_dll.lib or adns_dlld.lib
Other required libraries: C runtime libraries, Ws2_32.lib, Iphlpapi.lib

adns as a static library

The static library comes in two versions,

adns_lib.lib - normal runtime version
adns_libd.lib - debug version with symbolic information

Header file: adns.h
Library: adns_lib.lib or adns_libd.lib
Other required libraries: C runtime libraries, Ws2_32.lib, Iphlpapi.lib

Limitations in the Win32 version

The internal constancy check functions are not implemented due to use of GNU C extensions in the original code.
