TICKIT_RECT_INTERSECT(3) Library Functions Manual TICKIT_RECT_INTERSECT(3) NAME tickit_rect_intersect - obtain the intersection of two rectangles SYNOPSIS #include <tickit.h> bool tickit_rect_intersect(TickitRect *dst, const TickitRect *a, const TickitRect *b); Link with -ltickit. DESCRIPTION tickit_rect_intersect() tests if the two rectangles given by a and b inter- sect and if so, initialises the rectangle structure given by dst to contain it. It returns true if it did this. If the two given rectangles do not in- tersect then it returns false and does not modify the structure given by dst. dst may be equal to either a or b, or it may refer to a distinct rectangle structure. The two source rectangles are read before the result is written. To simply test if two given rectangles intersect without obtaining the ac- tual intersection region, use tickit_rect_intersects(3). RETURN VALUE tickit_rect_intersect() returns true if the rectangles intersect, and false if not.
