And you can use grep tricks :-)
$ errno '[dD]evice'
#define ENXIO 6 /* Device not configured */
#define ENOTBLK 15 /* Block device required */
#define EBUSY 16 /* Device busy */
#define EXDEV 18 /* Cross-device link */
#define ENODEV 19 /* Operation not supported by device */
#define ENOTTY 25 /* Inappropriate ioctl for device */
#define ENOSPC 28 /* No space left on device */
