RequestStart

ERESULT RequestStart();

Parameters

None

Return value

An ERESULT value describing the status known up to that point.

Description

Requests the camera driver to start sending frames. Camera devices are often asynchronous, and the status will be sent to OnCameraChange, either during the function call, or later as part of an event. If the success is known at the time of the call, the function will return it, otherwise E_OK is returned.
