voidinput_event(structinput_dev* dev, unsigned int type, unsigned int code, int value) report new input event Parameters structinput_dev*devdevice that generated the eventunsignedinttypetype of the eventunsignedintcodeevent codeintvaluevalue of the event
Description This function should be used by drivers implementing various input devices to report input events. See alsoinput_inject_event(). NOTE input_event()may be safely used right after input device was allocated withinput_allocate_device(), even before it is registered withinput_register_device(), but the event will not reach any of the input handlers. Such early invocation ofinput_event()may be used to ‘seed’ initial state of a switch or initial position of absolute axis, etc.
