HOWTO: Query the NDIS Version at Run Time

ID: Q195391

The information in this article applies to:

Microsoft Win32 Device Driver Kit (DDK) for Windows NT, versions 3.51, 4.0

SUMMARY

This article explains how drivers using NDIS (miniports, protocols) can query the current NDIS version at run time. This is particularly useful when you need to make changes to legacy drivers to adapt to later versions of NDIS.

Sample Code


   NDIS_STRING VersionStr = NDIS_STRING_CONST("NdisVersion");
   PNDIS_CONFIGURATION_PARAMETER ReturnedValue;

   NdisReadConfiguration(&Status,
                         &ReturnedValue,
                         ConfigHandle,
                         &VersionStr,
                         NdisParameterInteger);
   if (Status == NDIS_STATUS)
   {
           // 
           // The returned value has the NDIS version of the form
           // 0xMMMMmmmm, where MMMM is major version and mmmm is minor
           // version so 0x00050000 is 5.0
           // 
           Version = ReturnedValue->ParameterData.IntegerData;
   }
