PRADIUS_EXTENSION_INIT callback function (authif.h)

Note  Internet Authentication Service (IAS) was renamed Network Policy Server (NPS) starting with Windows Server 2008. The content of this topic applies to both IAS and NPS. Throughout the text, NPS is used to refer to all versions of the service, including the versions originally referred to as IAS.
The RadiusExtensionInit function is an application-defined function and is called by NPS while the service is starting up. Use RadiusExtensionInit to perform any initialization operations for the Extension DLL.



DWORD PradiusExtensionInit()


This callback function has no parameters.

Return value

If the function succeeds, the return value is NO_ERROR.

If the function fails, the return value should be an appropriate error code from WinError.h.
