FWPM_SUBLAYER0 structure (fwpmtypes.h)

The FWPM_SUBLAYER0 structure stores the state associated with a sublayer.

Syntax

typedef struct FWPM_SUBLAYER0_ {
  GUID               subLayerKey;
  FWPM_DISPLAY_DATA0 displayData;
  UINT32             flags;
  GUID               *providerKey;
  FWP_BYTE_BLOB      providerData;
  UINT16             weight;
} FWPM_SUBLAYER0;

Members

subLayerKey

Uniquely identifies the sublayer. See Filtering Sublayer Identifiers for a list of built-in sublayers.

If the GUID is zero-initialized in the call to FwpmSubLayerAdd0, the Base Filtering Engine (BFE) will generate one.

displayData

Allows sublayers to be annotated in human-readable form. The FWPM_DISPLAY_DATA0 structure is required.

flags

Possible values:

providerKey

Uniquely identifies the provider that manages this sublayer.

providerData

An FWP_BYTE_BLOB structure that contains optional provider-specific data that allows providers to store additional context info with the object.

weight

Weight of the sublayer.

Higher-weighted sublayers are invoked first.

Remarks

FWPM_SUBLAYER0 is a specific implementation of FWPM_SUBLAYER. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
