.Ft long
.Fn gethostid void
.Ft int
.Fn sethostid "long hostid"
.Sh DESCRIPTION
.Fn Sethostid
establishes a 32-bit identifier for the
current processor that is intended to be unique among all
UNIX systems in existence.  This is normally a DARPA Internet
address for the local machine.  This call is allowed only to the
super-user and is normally performed at boot time.
.Pp
.Fn Gethostid
returns the 32-bit identifier for the current processor.
.Pp
This function has been deprecated.
The hostid should be set or retrieved by use of
.Xr sysctl 3 .
.Sh SEE ALSO
.Xr sysctl 3 ,
.Xr gethostname 3 ,
.Xr sysctl 8 .
.Sh BUGS
32 bits for the identifier is too small.
.Sh HISTORY
The
.Fn gethostid
and
.Fn sethostid
syscalls appeared in 
.Bx 4.2
and were dropped in
.Bx 4.4 .
