Time-Based Notifications
You can notify the operating system to send joystick messages to an
application at regular time intervals by setting the fChanged parameter of joySetCapture to FALSE and by specifying the interval length between successive messages.
To do this, assign the uPeriod parameter a value between the minimum and maximum polling frequencies for the
joystick. You can determine this range by using the joyGetDevCaps function, which fills the wPeriodMin and wPeriodMax members in the JOYCAPS structure. If the uPeriod value is outside the range of valid polling frequencies for the joystick, the
joystick driver uses the minimum or maximum polling frequency, whichever is
closer to the uPeriod value.
Note Windows sets up a timer event with each call to joySetCapture.
