STRUCT 
INPUT_HANDLER(9) 					  Input Subsystem					   STRUCT INPUT_HANDLER(9)

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);
	 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);
	 const struct file_operations * fops;
	 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

       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

       fops
	   file operations this driver implements

       minor
	   beginning of range of 32 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.

NAME

       struct_device_driver - The basic device driver structure

SYNOPSIS

       struct device_driver {
	 const char * name;
	 struct bus_type * bus;
	 struct module * owner;
	 const char * mod_name;
	 bool suppress_bind_attrs;
	 const struct of_device_id * of_match_table;
	 const struct acpi_device_id * acpi_match_table;
	 int (* probe) (struct device *dev);
	 int (* remove) (struct device *dev);
	 void (* shutdown) (struct device *dev);
	 int (* suspend) (struct device *dev, pm_message_t state);
	 int (* resume) (struct device *dev);
	 const struct attribute_group ** groups;
	 const struct dev_pm_ops * pm;
	 struct driver_private * p;
       };

MEMBERS

       name
	   Name of the device driver.

       bus
	   The bus which the device of this driver belongs to.

       owner
	   The module owner.

       mod_name
	   Used for built-in modules.

       suppress_bind_attrs
	   Disables bind/unbind via sysfs.

       of_match_table
	   The open firmware table.

       acpi_match_table
	   The ACPI match table.

       probe
	   Called to query the existence of a specific device, whether this driver can work with it, and bind the driver to a specific device.

       remove
	   Called when the device is removed from the system to unbind a device from this driver.

       shutdown
	   Called at shut-down time to quiesce the device.

       suspend
	   Called to put the device to sleep mode. Usually to a low power state.

       resume
	   Called to bring a device from sleep mode.

       groups
	   Default attributes that get created by the driver core automatically.

       pm
	   Power management operations of the device which matched this driver.

       p
	   Driver core's private data, no one other than the driver core can touch this.

DESCRIPTION

       The device driver-model tracks all of the drivers known to the system. The main reason for this tracking is to enable the driver core to
       match up drivers with new devices. Once drivers are known objects within the system, however, a number of other things become possible.
       Device drivers can export information and configuration variables that are independent of any specific device.
