IOCTL_BATTERY_SUPPORTSCHANGENOTIFICATION (Windows Embedded CE 6.0)

1/6/2010

This IOCTL indicates whether the battery driver can report whether the batteries were changed. The DeviceIoControl function calls this IOCTL.

Parameters

• hDevice
  [in] Handle to the device that is to perform the operation. To obtain a device handle, call the CreateFile function.

• dwIoControlCode
  [in] Set to IOCTL_BATTERY_SUPPORTSCHANGENOTIFICATION.

• pInBuf
  [in] Set to NULL.

• InBufLen
  [in] Set to zero.

• pOutBuf
  [out] Pointer to a BOOL that will be set to TRUE if the battery supports change notification, or FALSE otherwise.

• OutBufLen
  [in] Set to sizeof(BOOL).

• lpBytesReturned
  [out] Long pointer to a variable that receives the size, in bytes, of the data stored into the buffer pointed to by lpOutBuffer.

• lpOverlapped
  [in] Ignored; set to NULL.

Return Values

If successful, DeviceIoControl returns TRUE and *pdwBytesTransferred will be sizeof(BOOL). Otherwise, DeviceIoControl returns FALSE. In case of failure, GetLastError contains an error status.
