Use the joyGetPos function to determine whether a given joystick is physically attached to the system. If the specified joystick is not connected, joyGetPos returns a JOYERR_UNPLUGGED error value.

The joyGetNumDevs function returns the number of joysticks supported by the current driver or zero if no driver is installed.
