IOCTL_ACC_CALIBRATESENSOR (Compact 7)
3/12/2014
This I/O control message calibrates the accelerometer sensor. Send this message with DeviceIoControl.
Syntax
BOOL DeviceIoControl(
HANDLE hDevice, // handle to the device
DWORD dwIoControlCode, // use IOCTL_ACC_CALIBRATESENSOR
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
[in] Handle to the device. To obtain a device handle, call CreateFile.
- dwIoControlCode
[in] Control code for the operation. Use IOCTL_ACC_CALIBRATESENSOR for this operation.
- lpInBuffer
[in] Set to NULL.
- nInBufferSize
[in] Set to zero
- lpOutBuffer
[in][out] Pointer to a DWORD that contains an error code.
- nOutBufferSize
[in] Set to sizeof(DWORD).
- lpBytesReturned
[out] Pointer to a DWORD giving the length of the returned data.
- lpOverlapped
[in] Ignored, set to NULL.
Remarks
The accelerometer should be in ACC_CONFIG_CALIBRATION_MODE prior to calling this IOCTL.
Return Values
Returns TRUE if successful; otherwise, returns FALSE.
Remarks
To get extended error information, call GetLastError. GetLastError may return other standard error messages as appropriate.
