size_t tickit_rectset_rects(const TickitRectSet *trs);
size_t tickit_rectset_get_rect(const TickitRectSet *trs,

DESCRIPTION¶
tickit_rectset_rects() returns the number of rectangular regions stored by the rectangle set.tickit_rectset_get_rect() copies the region representing the rectangle at index i into the variable pointed to by rect, and returns 1. If i is an invalid index for this set then 0 is returned instead.
tickit_rectset_get_rects() copies at most n regions into the array given by rects, and returns the number of regions it copied (which may be fewer than the total stored, if the array was of insufficient size).
