Name
exit()
Description
Quits/stops/exits the program. Programs without a draw() function
 exit automatically after the last line has run, but programs with
 draw() run continuously until the program is manually stopped or
 exit() is run.
 
 Rather than terminating immediately, exit() will cause the sketch
 to exit after draw() has completed (or after setup()
 completes if called during the setup() function).
 
 For Java programmers, this is not the same as System.exit().
 Further, System.exit() should not be used because closing out an
 application while draw() is running may cause a crash
 (particularly with P3D).
Examples
void draw() { line(mouseX, mouseY, 50, 50); } void mousePressed() { exit(); }
Syntax
exit()
Return
void
