RTEMS_GENERIC_BLOCK_DEVICE_DRIVER_ENTRIES

#define RTEMS_GENERIC_BLOCK_DEVICE_DRIVER_ENTRIES

Value:

rtems_blkdev_generic_open, \
  rtems_blkdev_generic_close, \
  rtems_blkdev_generic_read, \
  rtems_blkdev_generic_write, \
  rtems_blkdev_generic_ioctl

The device driver interface conventions suppose that a driver may contain an initialize, open, close, read, write and IO control entry points. These primitives (except initialize) can be implemented in a generic fashion based upon the supplied block device driver IO control handler. Every block device driver should provide an initialize entry point, which registers the appropriate IO control handler.
