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 2000 professional. The library comes as a dll. 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.

Please report any bugs or problems with the Win32 version to jgaa@jgaa.com

Current ported version

Supported compilers

The library is tested under Windows 2000, but should work with all versions from Windows NT 4 and up, and Windows98 and up. Windows95 is not supported. If you want to use the library in your own C/C++ project, you must set the following manifests before including adns.h:

#define ADNS_MAP_UNIXAPI
#define ADNS_DLL

ADNS_MAP_UNIXAPI will enable the Win32 port in the header-files (else, they will use the defauts for a UNIX system)

ADNS_DLL will enable linking to the exported DLL functions. Currently I have only made the DLL available. There are two reasons for this: 

  1. The DNS protocol is a mess - and it's difficult to make a foolproof implementation. If a security-problem is found (or other bugs) - the fix can usually be deployed just by replacing the DLL. 
  2. The GPL/LGPL license of ADNS (see GPL-vs-LGPL) will allow you to use the .dll in your project - as far as I can tell. A statically linked version will only be allowed in GPL licensed projects.
