- 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.
