ENOIOCTLCMD?

Can somebody explain the use of ENOIOCTLCMD? There are order of 170
uses in the kernel, but I don't see any guidelines for that use (nor
what prevents it from being seen by user programs).

Thanks.

errno.h:

>/* Should never be seen by user programs */
>#define ERESTARTSYS 512
>#define ERESTARTNOINTR 513
>#define ERESTARTNOHAND 514 /* restart if no handler.. */
>#define ENOIOCTLCMD 515 /* No ioctl command */
