Typedefs
typedef rtems_status_code	rtems_device_driver
	This type shall be used in device driver entry declarations and definitions.
typedef uint32_t	rtems_device_major_number
	This integer type represents the major number of devices.
typedef uint32_t	rtems_device_minor_number
	This integer type represents the minor number of devices.
typedef rtems_device_driver(*	rtems_device_driver_entry) (rtems_device_major_number, rtems_device_minor_number, void *)
	Device driver entries shall have this type.

Functions
rtems_status_code	rtems_io_register_driver (rtems_device_major_number major, const rtems_driver_address_table *driver_table, rtems_device_major_number *registered_major)
