  DWORD Ioctl,
  PUCHAR pInBuf,
  DWORD InBufLen, 
  PUCHAR pOutBuf,
  DWORD OutBufLen,
  PDWORD pdwBytesTransferred
);

  • 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.
