NAME

       struct_input_handler - implements one of interfaces for input devices

SYNOPSIS

       struct input_handler {
	 void * private;
	 void (* event) (struct input_handle *handle, unsigned int type, unsigned int code, int value);
	 void (* events) (struct input_handle *handle,const struct input_value *vals, unsigned int count);
	 bool (* filter) (struct input_handle *handle, unsigned int type, unsigned int code, int value);
	 bool (* match) (struct input_handler *handler, struct input_dev *dev);
	 int (* connect) (struct input_handler *handler, struct input_dev *dev, const struct input_device_id *id);
	 void (* disconnect) (struct input_handle *handle);
	 void (* start) (struct input_handle *handle);
	 bool legacy_minors;
	 int minor;
	 const char * name;
	 const struct input_device_id * id_table;
	 struct list_head h_list;
	 struct list_head node;
       };

MEMBERS

       private
	   driver-specific data

       event
	   event handler. This method is being called by input core with interrupts disabled and dev->event_lock spinlock held and so it may not
	   sleep

       events
	   event sequence handler. This method is being called by input core with interrupts disabled and dev->event_lock spinlock held and so it
	   may not sleep

       filter
	   similar to event; separates normal event handlers from "filters".

       match
	   called after comparing device's id with handler's id_table to perform fine-grained matching between device and handler

       connect
	   called when attaching a handler to an input device

       disconnect
	   disconnects a handler from input device

       start
	   starts handler for given handle. This function is called by input core right after connect method and also when a process that
	   "grabbed" a device releases it

       legacy_minors
	   set to true by drivers using legacy minor ranges

       minor
	   beginning of range of 32 legacy minors for devices this driver can provide

       name
	   name of the handler, to be shown in /proc/bus/input/handlers

       id_table
	   pointer to a table of input_device_ids this driver can handle

       h_list
	   list of input handles associated with the handler

       node
	   for placing the driver onto input_handler_list

DESCRIPTION

       Input handlers attach to input devices and create input handles. There are likely several handlers attached to any given input device at
       the same time. All of them will get their copy of input event generated by the device.

       The very same structure is used to implement input filters. Input core allows filters to run first and will not pass event to regular
       handlers if any of the filters indicate that the event should be filtered (by returning true from their filter method).

       Note that input core serializes calls to connect and disconnect methods.
