INPUT_EVENT(9)							  Input Subsystem						    INPUT_EVENT(9)

NAME

       input_event - report new input event

SYNOPSIS

       void input_event(struct input_dev * dev, unsigned int type, unsigned int code, int value);

ARGUMENTS

       dev
	   device that generated the event

       type
	   type of the event

       code
	   event code

       value
	   value of the event

DESCRIPTION

       This function should be used by drivers implementing various input devices to report input events. See also input_inject_event.

NOTE

       input_event may be safely used right after input device was allocated with input_allocate_device, even before it is registered with
       input_register_device, but the event will not reach any of the input handlers. Such early invocation of input_event may be used to 'seed'
       initial state of a switch or initial position of absolute axis, etc.

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.
