STRUCT SUBSYS_INTERF(9)           Device drivers infrastructure           STRUCT SUBSYS_INTERF(9)



NAME
       struct_subsys_interface - interfaces to device functions

SYNOPSIS
       struct subsys_interface {
         const char * name;
         struct bus_type * subsys;
         struct list_head node;
         int (* add_dev) (struct device *dev, struct subsys_interface *sif);
         void (* remove_dev) (struct device *dev, struct subsys_interface *sif);
       };

MEMBERS
       name
           name of the device function

       subsys
           subsytem of the devices to attach to

       node
           the list of functions registered at the subsystem

       add_dev
           device hookup to device function handler

       remove_dev
           device hookup to device function handler

DESCRIPTION
       Simple interfaces attached to a subsystem. Multiple interfaces can attach to a subsystem
       and its devices. Unlike drivers, they do not exclusively claim or control devices.
       Interfaces usually represent a specific functionality of a subsystem/class of devices.
