VBI_EVENT_CAPTION
event to be notified about pending changes (in case of "roll-up" mode that is with each new word received) and the vbi_page->dirty fields will mark the lines actually in need of updates, to speed up rendering.Although safe to do, this function is not supposed to be called from an event handler, since rendering may block decoding for extended periods of time.
FALSE
if some error occured.
