1/6/2010

This function signature is for the battery driver custom IOCTL handler. It implements the optional PDD IOCTL interface.

Syntax

typedef DWORD (*PFN_BATTERY_PDD_IOCONTROL)(
  DWORD dwContext,
  DWORD Ioctl,
  PUCHAR pInBuf,
  DWORD InBufLen, 
  PUCHAR pOutBuf,
  DWORD OutBufLen,
  PDWORD pdwBytesTransferred
);

Parameters

• dwContext
  [in] Handle to the device. To obtain a device handle, call the CreateFile function.

• Ioctl
  [in] IOCTL to invoke.

• pInBuf
  [in] Pointer to a buffer that contains the data required to perform the operation. Set to NULL if the Ioctl parameter specifies an operation that does not require input data.

• InBufLen
  [in] Size, in bytes, of the buffer pointed to by pInBuf.

• pOutBuf
  [out] Pointer to a buffer that receives the output data for the operation. Set to NULL if the dwIoControlCode parameter specifies an operation that does not produce output data.

• OutBufLen
  [in] Size, in bytes, of the buffer pointed to by lpOutBuffer.

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