The architecture for RADIUS Extension DLLs supports the following exported functions.

RadiusExtensionFreeAttributes

RadiusExtensionInit

RadiusExtensionProcess

RadiusExtensionProcess2

RadiusExtensionProcessEx

RadiusExtensionTerm

The RadiusExtensionInit and RadiusExtensionTerm functions are optional. The Extension DLL may export RadiusExtensionProcess2 instead of RadiusExtensionProcess or RadiusExtensionProcessEx. If the Extension DLL exports RadiusExtensionProcess2, it does not need to export RadiusExtensionFreeAttributes. If the Extension DLL exports RadiusExtensionProcessEx, then it must also export RadiusExtensionFreeAttributes.

**Windows 2000/NT:  **The Extension DLL must export either RadiusExtensionProcess or RadiusExtensionProcessEx. If the Extension DLL exports RadiusExtensionProcessEx, then it must also export RadiusExtensionFreeAttributes.

When IAS calls an implementation of RadiusExtensionProcess2, IAS passes the function a pointer to a RADIUS_EXTENSION_CONTROL_BLOCK structure. This structure contains function pointers to the following additional functions provided by IAS:

GetRequest

GetResponse

SetResponseType

The functions GetRequest and GetResponse return pointers to a structure of type RADIUS_ATTRIBUTE_ARRAY. This structure contains function pointers to the following functions provided by IAS:

Add

AttributeAt

GetSize

InsertAt

RemoveAt

SetAt
