getTouch()

template<int max_touch_points>

TouchResult roo_display::BasicTouchDevice< max_touch_points >::getTouch ( TouchPoint *  points, int  max_points  )

overridevirtual

Read the current touch state.

If no touch is registered, returns {.touch_points = 0} and does not modify points. If $k$ touch points are registered, writes min(k, max_points) entries to points, and returns {.touch_points = k}. In both cases, the returned timestamp is the detection time.

Parameters

points	Output buffer for touch points.
max_points	Capacity of points.

Returns

Touch result metadata.
