The .Fa namelen argument specifies the size of the .Fa name array. The returned name is null-terminated unless insufficient space is provided.

p The .Fn setdomainname function sets the NIS domain name of the host machine to be .Fa name , which has length .Fa namelen . This call is restricted to the super-user and is normally used only when the system is bootstrapped. .Sh RETURN VALUES .Rv -std .Sh ERRORS The following errors may be returned by these calls: l -tag -width Er t Bq Er EFAULT The .Fa name or .Fa namelen argument gave an invalid address. t Bq Er EPERM The caller tried to set the hostname and was not the super-user. .El .Sh SEE ALSO .Xr gethostid 3 , .Xr gethostname 3 , .Xr sysctl 3 .Sh HISTORY The .Fn getdomainname function appeared in x 4.2 . .Sh BUGS Domain names are limited to .Dv MAXHOSTNAMELEN (from n sys/param.h ) characters, currently 256.
