IStiUSD::RawWriteData method (stiusd.h)

A still image minidriver's IStiUSD::RawWriteData method writes data to a still image device.

Syntax

HRESULT RawWriteData(
  LPVOID       lpBuffer,
  DWORD        nNumberOfBytes,
  LPOVERLAPPED lpOverlapped
);

Parameters

lpBuffer

Caller-supplied pointer to a buffer containing data to be sent to the device.

nNumberOfBytes

Caller-supplied number of bytes to be written. This is the number of bytes in the buffer pointed to by lpBuffer.

lpOverlapped

Optional, caller-supplied pointer to an OVERLAPPED structure (described in the Microsoft Windows SDK documentation).

Return value

If the operation succeeds, the method should return S_OK. Otherwise, it should return one of the STIERR-prefixed error codes defined in stierr.h.

Remarks

A still image minidriver typically implements this method by calling WriteFile (described in the Windows SDK documentation).
