The joystick is an input device that provides position information. It is an add-itional supported input device, not a replacement for the mouse. All absolute-position devices, including touch screens, digitizing tablets, and light pens, can use the joystick services to provide position and button information to applications.
The joystick services are loaded when Windows is started. The joystick services can monitor two joysticks, each with two- or three-axis movement, and up to four buttons. Applications access the joystick services through the set of functions described in this section.
Note:
The driver for the IBM Game Adapter (IBMJOY.DRV) supports two 2-axis joysticks or one 3-axis joystick.
