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).
