3/26/2014

This structure is used for enumerating filters.

Syntax

typedef struct FWPM_FILTER_ENUM_TEMPLATE0_ {
  GUID* providerKey;
  GUID layerKey;
  FWP_FILTER_ENUM_TYPE enumType;
  UINT32 flags;
  FWPM_PROVIDER_CONTEXT_ENUM_TEMPLATE0* providerContextTemplate;
  UINT32 numFilterConditions;
  FWPM_FILTER_CONDITION0* filterCondition;
  UINT32 actionMask;
  GUID* calloutKey;
} FWPM_FILTER_ENUM_TEMPLATE0;

Members

• providerKey
  Uniquely identifies the provider associated with this filter.

• layerKey
  Layer whose fields are to be enumerated.

• enumType
  A FWP_FILTER_ENUM_TYPE value that determines how the filter conditions are interpreted.

• flags
  The possible values are listed in the Remarks section below.

• providerContextTemplate
  A FWPM_PROVIDER_CONTEXT_ENUM_TEMPLATE0 structure that is used to limit the number of filters enumerated. If non-NULL, only enumerate filters whose provider context matches the template.

• numFilterConditions
  Number of filter conditions. If zero, then all filters match.

• filterCondition
  An array of FWPM_FILTER_CONDITION0 structures that contain distinct filter conditions (duplicated filter conditions will generate an error).

• actionMask
  Only filters whose action type contains at least one of the bits in actionMask will be returned.

  Possible values are listed in the Remarks section below.

• calloutKey
  Uniquely identifies the callout.

Remarks

The following is a list of the possible values for the flags data member.

The following is a list of the possible values for the actionMask data member:

Value	Meaning
0xFFFFFFFF	Ignore the filter's action type when enumerating.
FWP_ACTION_FLAG_CALLOUT	Enumerate callouts only. Note: calloutKey must not be NULL.
