STRUCT INPUT_POLLED_(9)                  Input Subsystem                  STRUCT INPUT_POLLED_(9)



NAME
       struct_input_polled_dev - simple polled input device

SYNOPSIS
       struct input_polled_dev {
         void * private;
         void (* open) (struct input_polled_dev *dev);
         void (* close) (struct input_polled_dev *dev);
         void (* poll) (struct input_polled_dev *dev);
         unsigned int poll_interval;
         unsigned int poll_interval_max;
         unsigned int poll_interval_min;
         struct input_dev * input;
       };

MEMBERS
       private
           private driver data.

       open
           driver-supplied method that prepares device for polling (enabled the device and maybe
           flushes device state).

       close
           driver-supplied method that is called when device is no longer being polled. Used to
           put device into low power mode.

       poll
           driver-supplied method that polls the device and posts input events (mandatory).

       poll_interval
           specifies how often the poll method should be called. Defaults to 500 msec unless
           overridden when registering the device.

       poll_interval_max
           specifies upper bound for the poll interval. Defaults to the initial value of
           poll_interval.

       poll_interval_min
           specifies lower bound for the poll interval. Defaults to 0.

       input
           input device structure associated with the polled device. Must be properly initialized
           by the driver (id, name, phys, bits).

DESCRIPTION
       Polled input device provides a skeleton for supporting simple input devices that do not
       raise interrupts but have to be periodically scanned or polled to detect changes in their
       state.
