Subject: 386BSD: PATCH to add domainname(1)

Here's support for the domainname system calls and programs.  This
patch is required for the YP client stuff that I will be shipping in
probably two weeks (beta).

I'm implimenting my YP stuff on a network of Sun's. I'd like to have a
few beta testers who have different YP master/server machines, ie.
SGI, Ultrix, HP. Hopefully I can get people who know a bit of RPC
programming. Drop me a note.

I've sent a copy of this to <terry@cs.weber.edu> as well for inclusion
into the patchkit. Could someone ensure that William Jolitz gets a
copy of this so that it will be in the next release whenever that is
due? Thanks.

X.Sh DESCRIPTION
X.Fn Getdomainname
Xreturns the standard host name for the current processor, as
Xpreviously set by
X.Fn setdomainname .
XThe parameter
X.Fa namelen
Xspecifies the size of the

Xarray.  The returned name is null-terminated unless insufficient
Xspace is provided.

Xwhich has length
X.Fa namelen .
XThis call is restricted to the super-user and
Xis normally used only when the system is bootstrapped.
X.Sh RETURN VALUES
XIf the call succeeds a value of 0 is returned.  If the call
Xfails, a value of -1 is returned and an error code is
Xplaced in the global location
X.Va errno .
X.Sh ERRORS
XThe following errors may be returned by these calls:
X.Bl -tag -width Er
X.It Bq Er EFAULT
XThe
X.Fa name
Xor
X.Fa namelen
Xparameter gave an
Xinvalid address.
X.It Bq Er EPERM
XThe caller tried to set the domainname and was not the super-user.
