OID_TAPI_SET_MEDIA_MODE uses the NDIS_TAPI_SET_MEDIA_MODE structure when it requests the miniport driver to change a call's media mode as stored in the LINE_CALL_INFO structure for that call.

Support for this request is mandatory.

Syntax

typedef struct _NDIS_TAPI_SET_MEDIA_MODE { 
  ULONG ulRequestID; 
  HDRV_CALL hdCall; 
  ULONG ulMediaMode; 
} NDIS_TAPI_SET_MEDIA_MODE, *PNDIS_TAPI_SET_MEDIA_MODE;

Members

  • ulRequestID
    [in] Reserved.
  • hdCall
    [in] Specifies the miniport driver's handle to the call for which it should change the media mode.

  • ulMediaMode
    [in] Specifies the new media mode(s) for the call as one or more of the LINEMEDIAMODE_XXX flags.

    If the LINEMEDIAMODE_UNKNOWN flag is set, other media mode flags also can be set. Such a combination of flags specifies that the call's media mode is not fully determined, but that it has been narrowed down to a subset of possible media modes. If the LINEMEDIAMODE_UNKNOWN flag is clear, only a single media mode can be specified.

Remarks

The MiniportSetInformation function can return one of the following:

  • NDIS_STATUS_SUCCESS
  • NDIS_STATUS_PENDING
  • NDIS_STATUS_TAPI_INVALCALLHANDLE
  • NDIS_STATUS_TAPI_INVALMEDIAMODE
  • NDIS_STATUS_TAPI_RESOURCEUNAVAIL
  • NDIS_STATUS_FAILURE

Requirements

Header ndistapi.h, ntddndis.h
Windows Embedded CE Windows CE .NET 4.0 and later
