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.
