CIGAL Reference Manual, Chapter 6 (RealTime): r_getxy
usage: r_getxy opflg eflag ltime Point [WaitFlag]
R_GETXY is a REALTIME operator. It reads the position of the mouse cursor and stores the result in POINT (an array of 2 short integers: x,y). Normally, R_GETXY waits for a mouse click or keyboard key press before returning the position; this can be avoided by specifying WAITFLAG as 0.
