NAME
struct_input_handler - implements one of interfaces for input devicesSYNOPSIS
-
struct input_handler { void * private; void (* event) (struct input_handle *handle, unsigned int type, unsigned int code, int value); 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; const struct input_device_id * blacklist; 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
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
blacklist
- pointer to a table of input_device_ids this driver should ignore even if they match id_table
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.
Note that input core serializes calls to connect and disconnect methods.
