IStiDeviceControl::GetMyDevicePortName method (stiusd.h)
The IStiDeviceControl::GetMyDevicePortName method allows a user-mode still image minidriver to obtain a device's port name.
Syntax
HRESULT GetMyDevicePortName(
LPWSTR lpszDevicePath,
DWORD cwDevicePathSize
);
Parameters
lpszDevicePath
Caller-supplied pointer to a buffer to receive the device's port name.
cwDevicePathSize
Caller-supplied number of characters (of type TCHAR) in the buffer pointed to by lpszDevicePath.
Return value
If the operation succeeds, the method returns S_OK. Otherwise, it returns one of the STIERR-prefixed error codes defined in stierr.h.
Remarks
The path name that a still image minidriver receives by calling IStiDeviceControl::GetMyDevicePortName can be used as an input argument to CreateFile (described in the Microsoft Windows SDK documentation).
A still image minidriver receives an IStiDeviceControl interface pointer as an input argument to its IStiUSD::Initialize method.
