1/6/2010

This structure is used by HCI stack layer for matching command completion to HCI stack client issuing the command.

typedef struct _packet_marker {
  unsigned int fMarker;
  union {
    BD_ADDR ba;
    unsigned short connection_handle;
  };
} PacketMarker;

Members

  This member may be one of the following.

  Marker	Value
  BTH_MARKER_NONE	0
  BTH_MARKER_CONNECTION	1
  BTH_MARKER_ADDRESS	2

• ba
  Depending on fMarker, ba contains the Bluetooth address.

• connection_handle
  Depending on fMarker, connection_handle contains the connection handle associated with the command.

Remarks

The structure is used in conjunction with the following command to match asynchronous event associated with this command to the command itself.

typedef int (*HCI_CustomCode_In) (
  HANDLE          hDeviceContext,
  void*           pCallContext,
  unsigned short  usOpCode,
  unsigned short  cPacketSize,
  unsigned char*  pPacket,
  PacketMarker*   pMarker,
  unsigned char   cEvent
);

Requirements

Header	bt_ddi.h
Windows Embedded CE	Windows CE .NET 4.0 and later
