3/26/2014

This I/O control message retrieves the mode for active baseband connections. Send this message with DeviceIoControl.

Syntax

BOOL DeviceIoControl(
    HANDLE hDevice,           // handle to device
    DWORD dwIoControlCode,    // use BTH_HCI_IOCTL_GET_HANDLE_MODE
    LPVOID lpInBuffer,        // pointer to input buffer
    DWORD nInBufferSize,      // input buffer size
    LPVOID lpOutBuffer,       // pointer to output buffer
    DWORD nOutBufferSize,     // output buffer size
    LPDWORD lpBytesReturned,  // number of bytes returned
    OVERLAPPED lpOverlapped   // pointer to OVERLAPPED structure
);

Parameters

• hDevice
  The handle to the device.

• dwIoControlCode
  [in] Control code for the operation. Use BTH_HCI_IOCTL_GET_HANDLE_MODE for this operation.

• lpInBuffer
  [in] Aligned pointer to an unsigned short containing a connection handle.

• nInBufferSize
  [in] Set to 2.

  Value	Mode
  0x00	Active
  0x01	Hold
  0x02	Sniff
  0x03	Park

• nOutBufferSize
  [out] Set to sizeof(unsigned char).

• lpBytesReturned
  [out] Equals nOutBufferSize.

• lpOverlapped
  Ignored.
