mouse_callback: User specified mouse callback. Allegro game programming library.
NAMEmouse_callback - User specified mouse callback. Allegro game programming library.
DESCRIPTIONCalled by the interrupt handler whenever the mouse moves or one of the buttons changes state. This function must be in locked memory, and must execute _very_ quickly! It is passed the event flags that triggered the call, which is a bitmask containing any of the values MOUSE_FLAG_MOVE, MOUSE_FLAG_LEFT_DOWN, MOUSE_FLAG_LEFT_UP, MOUSE_FLAG_RIGHT_DOWN, MOUSE_FLAG_RIGHT_UP, MOUSE_FLAG_MIDDLE_DOWN, MOUSE_FLAG_MIDDLE_UP, and MOUSE_FLAG_MOVE_Z. Note that even if the mouse has more than three buttons, only the first three can be trapped using a callback.
