More advanced programmers in C can be notified of events such as a change of the state of the mouse and the keyboard by making some of their own functions be automatically called by the bx-lib. This requires the knowledge that functions may be passed as arguments to other functions. The notifications occur when the bx-lib "has the hand" on the system, that is, during the execution of functions such as bx_wait(), bx_loop() and bx_show_canvas(). More...
