FWPS_INCOMING_VALUES0 structure (fwpstypes.h)

The FWPS_INCOMING_VALUES0 structure defines data values that are passed by the filter engine to a callout's classifyFn callout function.

Syntax

typedef struct FWPS_INCOMING_VALUES0_ {
  UINT16               layerId;
  UINT32               valueCount;
  FWPS_INCOMING_VALUE0 *incomingValue;
} FWPS_INCOMING_VALUES0;

Members

layerId

The run-time filtering layer identifier for the filtering layer at which the data values were obtained. For more information, see Run-time Filtering Layer Identifiers.

valueCount

The number of FWPS_INCOMING_VALUE0 structures in the array pointed to by the incomingValue member.

incomingValue

A pointer to an array of FWPS_INCOMING_VALUE0 structures that contain the data values.

Remarks

The filter engine passes a pointer to an FWPS_INCOMING_VALUES0 structure to a callout's

<a href="https://docs.microsoft.com/windows-hardware/drivers/ddi/content/fwpsk/nc-fwpsk-fwps_callout_classify_fn0">classifyFn</a> callout function. 
The values in this array depend on the **layerId**; each layer has an associated set of available indexes as outlined in the **FWPS_FIELDS_&lt;LAYER_ID&gt;** enumerations. 
For example, for the **ALE_AUTH_CONNECT_V4** layer, the available indexes are listed in the [FWPS_FIELDS_ALE_AUTH_CONNECT_V4 enumeration](windows-hardware/drivers/ddi/fwpsk/ne-fwpsk-fwps_fields_ale_auth_connect_v4_).
