FwpsApplyModifiedLayerData0 function

The FwpsApplyModifiedLayerData0 function applies changes to layer-specific data made after a call to FwpsAcquireWritableLayerDataPointer0.

Note  FwpsApplyModifiedLayerData0 is a specific version of FwpsApplyModifiedLayerData. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
 

Syntax

void FwpsApplyModifiedLayerData0(
  UINT64 classifyHandle,
  PVOID  modifiedLayerData,
  UINT32 flags
);

Parameters

classifyHandle

The classification handle that identifies the callout driver's processing at the current layer. This handle is obtained by calling FwpsAcquireClassifyHandle0.

modifiedLayerData

The data buffer obtained by calling FwpsAcquireWritableLayerDataPointer0 with members modified by the callout driver. Supported data types are defined as structures.

flags

The options to use with this function call. This flag can have the following value.

Value Meaning
FWPS_CLASSIFY_FLAG_REAUTHORIZE_IF_MODIFIED_BY_OTHERS
When set, this flag specifies that data at the layer of the pended classify action should be reauthorized if another callout driver modifies the data before the classification is completed. Use this flag only with pended classify and not inline classify, as its use with inline classify can lead to indeterminate results. If you do call this API for inline classify, set flags to zero.

Return Value

None.

Remarks

FwpsApplyModifiedLayerData0 should be called once for every call made to FwpsAcquireWritableLayerDataPointer0, even if the callout driver didn't modify any data.
