3/12/2014

This structure defines a generic data value, which you can use primarily to supply incoming values to the Windows Filtering Platform (WFP) filter engine.

Syntax

typedef struct FWP_VALUE0_ {
  FWP_DATA_TYPE type;
  union {
    ;      // case(FWP_EMPTY)
    UINT8 uint8;
    UINT16 uint16;
    UINT32 uint32;
    UINT64* uint64;
    INT8 int8;
    INT16 int16;
    INT32 int32;
    INT64* int64;
    float float32;
    double* double64;
    FWP_BYTE_ARRAY16* byteArray16;
    FWP_BYTE_BLOB* byteBlob;
    SID* sid;
    FWP_BYTE_BLOB* sd;
    FWP_TOKEN_INFORMATION* tokenInformation;
    FWP_BYTE_BLOB* tokenAccessInformation;
    LPWSTR unicodeString;
  };
} FWP_VALUE0;

    Pointer to a system identifier (SID).

  • sd
    case(FWP_SECURITY_DESCRIPTOR_TYPE)

    Pointer to a security descriptor contained in an FWP_BYTE_BLOB structure.

  • tokenInformation
    case(FWP_TOKEN_INFORMATION_TYPE).

  • tokenAccessInformation
    case(FWP_TOKEN_ACCESS_INFORMATION_TYPE)

    Pointer to a null-terminated Unicode string.

Remarks

When you store IP addresses in FWP_UINT32 (uint32) format, or when you store IP port numbers in FWP_UINT16 (uint16) format, they are stored in host order, not network order.
