IStiDevice::DeviceReset method (sti.h)

  • Article

The IStiDevice::DeviceReset method resets a still image device to a known state.

Syntax

HRESULT DeviceReset();

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 IStiDevice::DeviceReset method resets the device by calling IStiUSD::DeviceReset, which is exported by vendor-supplied minidrivers.

Before calling IStiDevice::DeviceReset, clients of the IStiDevice COM interface must call IStillImage::CreateDevice to obtain an IStiDevice interface pointer, which provides access to a specified device.

A call to IStiDevice::DeviceReset must be preceded by a call to IStiDevice::LockDevice and followed by a call to IStiDevice::UnLockDevice.
