PRB: NDIS.H Header Has Incorrect NdisReadMcaPosInformation

Last reviewed: January 8, 1997
Article ID: Q122172

The information in this article applies to:

Microsoft Win32 Device Development Kit (DDK) for Windows NT, version 3.5

SYMPTOMS

Attempting to use NdisReadMcaPosInformation() in a Windows NT network driver may cause compiler warnings and/or undefined behavior at run time.

CAUSE

The function prototype for NdisReadMcaPosInformation is incorrect as listed in the header file NDIS.H. The third parameter is listed as an IN UINT; it should be an OUT PUINT.

RESOLUTION

Modify NDIS.H so that the function prototype for NdisReadMcaPosInformation is as follows:

VOID NdisReadMcaPosInformation(

        OUT PNDIS_STATUS Status,
        IN  NDIS_HANDLE WrapperConfigurationContext,
        OUT PUINT ChannelNumber,
        OUT PNDIS_MCA_POS_DATA McaData
        );

STATUS

This behavior is by design.
