FRAME_DESCRIPTOR

  • Article

The FRAME_DESCRIPTOR structure provides descriptive information about raw frames.

typedef struct _FRAME_DESCRIPTOR {
  LPBYTE FramePointer;
  __int64 TimeStamp;
  DWORD FrameLength;
  DWORD nBytesAvail;
  WORD Etype;
  BYTE Sap;
  BYTE LowProtocol;
  WORD LowProtocolOffset;
  GENERIC_PORT HighPort;
  WORD HighProtocolOffset;
} FRAME_DESCRIPTOR, 
 *LPFRAME_DESCRIPTOR;

Members

  • FramePointer
    Pointer to frame data.
  • TimeStamp
    System time, in microseconds, when the frame was captured. This time is typically used to determine the interval between the times two frames were captured.
  • FrameLength
    Length of the frame.
  • nBytesAvail
    Actual frame length copied.
  • Etype
    Etype name.
  • Sap
    SAP value.
  • LowProtocol
    Index of protocol found.
  • LowProtocolOffset
    Offset to protocol data obtained from LowProtocol.
  • HighPort
    Port of high protocol identified in LowProtocol.
  • HighProtocolOffset
    Offset to protocol data obtained from HighPort.
