  • Article

3/12/2014

To specify its driver characteristics, a filter driver initializes a NDIS_FILTER_DRIVER_CHARACTERISTICS structure and passes it to NDIS.

Syntax

typedef struct _NDIS_FILTER_DRIVER_CHARACTERISTICS {
  NDIS_OBJECT_HEADER  Header; 
  UCHAR  MajorNdisVersion;
  UCHAR  MinorNdisVersion;
  UCHAR  MajorDriverVersion;
  UCHAR  MinorDriverVersion;
  ULONG  Flags;
  NDIS_STRING  FriendlyName;
  NDIS_STRING  UniqueName;
  NDIS_STRING  ServiceName;
  SET_OPTIONS_HANDLER  SetOptionsHandler;
  FILTER_SET_FILTER_MODULE_OPTIONS_HANDLER  SetFilterModuleOptionsHandler;
  FILTER_ATTACH_HANDLER  AttachHandler;
  FILTER_DETACH_HANDLER  DetachHandler;
  FILTER_RESTART_HANDLER  RestartHandler;

  FILTER_SEND_NET_BUFFER_LISTS_COMPLETE_HANDLER  SendNetBufferListsCompleteHandler;
  FILTER_CANCEL_SEND_HANDLER  CancelSendNetBufferListsHandler;
  FILTER_RECEIVE_NET_BUFFER_LISTS_HANDLER  ReceiveNetBufferListsHandler;

} NDIS_FILTER_DRIVER_CHARACTERISTICS, *PNDIS_FILTER_DRIVER_CHARACTERISTICS;

Members

  • Header
    The NDIS_OBJECT_HEADER structure for the filter driver characteristics structure (NDIS_FILTER_DRIVER_CHARACTERISTICS). Set the Type member of the structure that Header specifies to NDIS_OBJECT_TYPE_FILTER_DRIVER_CHARACTERISTICS.

    To indicate the version of the NDIS_FILTER_DRIVER_CHARACTERISTICS structure, set the Revision member to one of the following values:

    • NDIS_FILTER_CHARACTERISTICS_REVISION_2
      Added the DirectOidRequestHandler, DirectOidRequestCompleteHandler, and CancelDirectOidRequestHandler members.

      Set the Size member to NDIS_SIZEOF_FILTER_DRIVER_CHARACTERISTICS_REVISION_2.

    • NDIS_FILTER_CHARACTERISTICS_REVISION_1
      Original version.

      Set the Size member to NDIS_SIZEOF_FILTER_DRIVER_CHARACTERISTICS_REVISION_1.

  • MajorNdisVersion
    The major version of NDIS that the driver is using. This value must be 0x06 or higher.
  • MinorNdisVersion
    The minor version of NDIS that the driver is using. The value must be 0x00 or higher.
  • MajorDriverVersion
    Reserved for the major version number of the filter driver. Filter drivers can specify any value that they require.
  • MinorDriverVersion
    Reserved for the minor version number of the filter driver. Filter drivers can specify any value that they require.
  • Flags
    Reserved for NDIS.
  • FriendlyName
    A Unicode string that represents the user-readable description of the filter driver.
  • UniqueName
    A Unicode string that represents the unique name for the filter driver. This name is unique within the system.
  • ServiceName
    A Unicode string that represents the service name of the filter driver. This is the service name that is defined in the driver's INF file.
  • SetOptionsHandler
    Specifies the entry point of the caller's FilterSetOptions function.
  • AttachHandler
    The entry point of the caller's FilterAttach function.
  • DetachHandler
    The entry point of the caller's FilterDetach function.
  • RestartHandler
    The entry point of the caller's FilterRestart function.
  • PauseHandler
    The entry point of the caller's FilterPause function.
  • SendNetBufferListsHandler
    The entry point of the caller's FilterSendNetBufferLists function. To bypass this function, set this member to NULL.
  • SendNetBufferListsCompleteHandler
    The entry point of the caller's FilterSendNetBufferListsComplete function. To bypass this function, set this member to NULL.
  • CancelSendNetBufferListsHandler
    The entry point of the caller's FilterCancelSendNetBufferListsfunction. To bypass this function, set this member to NULL.
  • ReceiveNetBufferListsHandler
    The entry point of the caller's FilterReceiveNetBufferLists function. To bypass this function, set this member to NULL.
  • ReturnNetBufferListsHandler
    The entry point of the caller's FilterReturnNetBufferLists function. To bypass this function, set this member to NULL.
  • OidRequestHandler
    The entry point of the caller's FilterOidRequest function. To bypass this function, set this member to NULL.
  • OidRequestCompleteHandler
    The entry point of the caller's FilterOidRequestComplete function. To bypass this function, set this member to NULL.
  • CancelOidRequestHandler
    The entry point of the caller's FilterCancelOidRequest function. To bypass this function, set this member to NULL.
  • DevicePnPEventNotifyHandler
    The entry point of the caller’s FilterDevicePnPEventNotify function. To bypass this function, set this member to NULL.
  • NetPnPEventHandler
    The entry point of the caller's FilterNetPnPEvent function. To bypass this function, set this member to NULL.
  • StatusHandler
    The entry point of the caller's FilterStatus function. To bypass this function, set this member to NULL.
  • DirectOidRequestHandler
    The entry point of the caller's FilterDirectOidRequest function. To bypass this function, set this member to NULL.
  • DirectOidRequestCompleteHandler
    The entry point of the caller's FilterDirectOidRequestComplete function. To bypass this function, set this member to NULL.
  • CancelDirectOidRequestHandler
    The entry point of the caller's FilterCancelDirectOidRequest function. To bypass this function, set this member to NULL.

Remarks

A filter driver calls the NdisFRegisterFilterDriver function to register its characteristics. This includes the default entry points for its filter driver functions (FilterXxx). The filter driver initializes a NDIS_FILTER_DRIVER_CHARACTERISTICS structure and passes a pointer to this structure in the FilterCharacteristics parameter of NdisFRegisterFilterDriver.
