From MSDN this is an API you can use to get the MAC address... Hope it
helps.
FILTEROBJECT
The FILTEROBJECT structure defines a single object of a display filter. The
FilterAddObject function uses FILTEROBJECT to build a display filter.
typedef struct _FILTEROBJECT { FILTERACTIONTYPE Action; HPROPERTY
hProperty; union { VALUETYPE Value; HPROTOCOL hProtocol; LPVOID
lpArray; LPPROTOCOLTABLETYPE lpProtocolTable; LPADDRESS lpAddress;
ULPLARGEINT lpLargeInt; ULPTIME lpTime; LPOBJECT_IDENTIFIER lpOID; };
union { WORD ByteCount; WORD ByteOffset; }; struct _FILTEROBJECT*
pNext;
} FILTEROBJECT, *LPFILTEROBJECT;Members
Action
Flag that specifies the FILTEROBJECT action. A flag can specify a
property, value, or operator.
The following table lists Action member property flags.
Value Meaning
FILTERACTION_PROPERTY Contains this property.
FILTERACTION_PROPERTYEXIST Indicates that a filter action property
is already defined.
The following table lists Action member value flags.
Value Meaning
FILTERACTION_VALUE Contains this value.
FILTERACTION_STRING Contains this string.
FILTERACTION_ARRAY Contains this array.
FILTERACTION_CONTAINSNC Indicates that a property contains a
case-insensitive substring.
FILTERACTION_CONTAINS Indicates that a property contains a case
sensitive substring.
FILTERACTION_ADDRESS Contains the MAC address.
FILTERACTION_ADDRESSANY Matches any MAC address.
FILTERACTION_FROM Indicates the From MAC address.
FILTERACTION_TO Indicates the To MAC address.
FILTERACTION_FROMTO Indicates a From/To pairing of MAC addresses.
FILTERACTION_LARGEINT Contains a large integer.
FILTERACTION_TIME Contains a SYSTEMTIME structure.
FILTERACTION_ADDR_ETHER Contains an Ethernet MAC address.
FILTERACTION_ADDR_TOKEN Contains a token ring MAC address.
FILTERACTION_ADDR_FDDI Contains a FDDI MAC address.
FILTERACTION_ADDR_IPX Contains an IPX MAC address.
FILTERACTION_ADDR_IP Contains an IP MAC address.
FILTERACTION_OID Contains an Object Identifier (OID).
The following table lists Action member operator flags.
Value Meaning
FILTERACTION_INVALID Indicates an invalid filter action.
FILTERACTION_AND Indicates a logical AND statement.
FILTERACTION_OR Indicates a logical OR statement.
FILTERACTION_XOR Indicates a logical exclusive OR (XOR) statement.
FILTERACTION_NOT Indicates a logical NOT statement.
FILTERACTION_EQUALNC Filter action is equal and case insensitive.
FILTERACTION_EQUAL Filter action is equal and case sensitive.
FILTERACTION_NOTEQUALNC Logical NOT statement is equal and case
insensitive.
FILTERACTION_NOTEQUAL Logical NOT statement is equal and is case
sensitive.
FILTERACTION_GREATERNC Filter action is greater than (>) and case
insensitive.
FILTERACTION_GREATER Filter action is greater than (>) and case
sensitive.
FILTERACTION_LESSNC Filter action is less than (<) and case
insensitive.
FILTERACTION_LESS Filter action is less than (<) and case sensitive.
FILTERACTION_GREATEREQUALNC Filter action is greater than or equal
to (>=) and case insensitive.
FILTERACTION_GREATEREQUAL Filter action is greater than or equal to
(>=) and case sensitive.
FILTERACTION_LESSEQUALNC Filter action is less than or equal to (<=)
and case insensitive.
FILTERACTION_LESSEQUAL Filter action is less than or equal to (<=)
and is case sensitive.
FILTERACTION_PLUS Add operator (+).
FILTERACTION_MINUS Subtract operator (-).
FILTERACTION_AREBITSON Indicates BIT-wise operation.
FILTERACTION_AREBITSOFF Indicates non-BIT-wise operation.
FILTERACTION_PROTOCOLSEXIST Indicates that the selected protocols
exist.
FILTERACTION_PROTOCOLEXIST Indicates that the selected protocol
exists.
FILTERACTION_ARRAYEQUAL Indicates that array contents are equal. The
flag must be used with a FILTERACTION_ARRAY structure.
FILTERACTION_DEREFPROPERTY Describes a pattern match at an offset
(in bytes), from the protocol.
FILTERACTION_OID_CONTAINS Evaluates a substring within an object
identifier. The action must be used with the FILTERACTION_OID structure.
FILTERACTION_OID_BEGINS_WITH Evaluates a substring that begins an
object identifier. The flag must be used with FILTERACTION_OID.
FILTERACTION_OID_ENDS_WITH Evaluates a substring that ends an object
identifier. The flag must be used with FILTERACTION_OID.
FILTERACTION_ADDR_VINES Contains a Vines MAC address.
FILTERACTION_EXPRESSION Contains an action expression.
FILTERACTION_BOOL Contains a BOOL data type.
FILTER_DIRECTION_NEXT Controls sequential direction (Next frame)
within a capture file.
FILTER_DIRECTION_PREV Controls sequential direction (Previous frame)
within a capture file.
hProperty
Handle to a property key.
Value
Value of an object.
hProtocol
Handle to display filter protocol.
lpArray
Pointer to an array.
lpProtocolTable
Pointer to a protocol list designed to test the existence of protocol in a
frame.
lpAddress
Pointer to the kernel type address. For example, MAC or IP.
lpLargeInt
Double DWORD used in Windows NT/Windows 2000 applications.
lpTime
Pointer to a SYSTEMTIME structure.
lpOID
Pointer to the OBJECT_IDENTIFIER (OID) structure.
ByteCount
Number of bytes in the frame.
ByteOffset
Offset byte value of the FILTEROBJECT structure used to compare arrays.
pNext
Reserved.
Requirements
Client: Included in Windows XP, Windows 2000 Professional, and Windows NT
Workstation 4.0.
Server: Included in Windows Server 2003, Windows 2000 Server, and Windows NT
Server 4.0.
Header: Declared in Filter.h.
