I'm looking for an XDR routine which will handle a null terminated
array of strings.  This is argv's and envp's type on modern UNIX
systems.  An example is char *envp[] = { "first", "second", NULL } ;

I suspect that the answer is a combination of xdr_array, xdr_pointer,
and xdr_wrapstring, but I can't quite get them together correctly.
Obviously, this problem can be worked around using a count (this
is an example in the XDR documentation), but the program I have now
uses a null terminated array, and it would be nice not to change it.

Thanks for any help.  I'll sumarize to the group if I get good answers.
