wCaps

Joystick capabilities The following flags define individual capabilities that a joystick might have:

JOYCAPS_HASZ	Joystick has z-coordinate information.
JOYCAPS_HASR	Joystick has rudder (fourth axis) information.
JOYCAPS_HASU	Joystick has u-coordinate (fifth axis) information.
JOYCAPS_HASV	Joystick has v-coordinate (sixth axis) information.
JOYCAPS_HASPOV	Joystick has point-of-view information.
JOYCAPS_POV4DIR	Joystick point-of-view supports discrete values (centered, forward, backward, left, and right).
JOYCAPS_POVCTS	Joystick point-of-view supports continuous degree bearings.

wMaxAxes

Maximum number of axes supported by the joystick.

wNumAxes

Number of axes currently in use by the joystick.

wMaxButtons

Maximum number of buttons supported by the joystick.

szRegKey

Null-terminated string containing the registry key for the joystick.

szOEMVxD

Null-terminated string identifying the joystick driver OEM.
