Subject: Missing ruserpass in libcompat
To: None <core@NetBSD.ORG>

The rexec() function in libcompat refers to the ruserpass function,
which doesn't seem to exist, for some reason, so I took this function
from the ftp sources, and got rid of all extraneous variables etc.
I've included the diffs to the /usr/src/lib/libcompat/Makefile, and
the /usr/src/lib/libcompat/4.3/ruserpass.[c3] files below.
I found these when I was trying to put pvm 3.3.7 on NetBSD. It seems
to work, now.
I also noticed that the manual page for rexec references the krcmd()
function, which is nowhere to be found.

+ .Dt RUSERPASS 3
+ .Os BSD 4.2
+ .Sh NAME
+ .Nm ruserpass
+ .Nd obtain remote account details from .netrc file
+ .Sh SYNOPSIS
+ .Ft int
+ .Fn ruserpass "char *host" "char **aname" "char **apass" "char **aacct"
+ .Sh DESCRIPTION
+ .Bf -symbolic
+ This interface is obsoleted by
+ .Xr krcmd 3 .
+ It is available from the compatibility library, libcompat.
+ .Ef
+ .Pp
+ The
+ .Fn ruserpass
+ function
+ looks up the
+ .Pa .netrc
+ file in the user's home directory
+ on the localhost, and determines the information
+ held therein for the remote host
+ .Fa host
+ This remote host can be specified using the host's name,
+ or its (partial) IP address.
+ If a match is found in the file, or the "default" and
+ "machine" directives are specified, the file
+ is searched for the remote username, the remote account
+ information, and the remote password information.
+ A warning will be printed on the local machine if the
+ .Pa .netrc
+ file is visible to other users.
+ .Sh RETURN VALUE
+ A return value of 0 is returned on successful search,
+ or if the user's
+ .Pa .netrc
+ file does not exist,
+ and -1 is returned if an error occurred.
+ .Sh SEE ALSO
+ .Xr rcmd 3 ,
+ .Xr rexecd 8
+ .Sh HISTORY
+ The
+ .Fn ruserpass
+ function appeared in
+ .Bx 4.2 .
