Message-ID: <20211013230405.32170-8-wwcohen@gmail.com> (raw)
In-Reply-To: <20211013230405.32170-1-wwcohen@gmail.com>

From: Keno Fischer <keno@juliacomputing.com>

This implements the darwin equivalent of the functions that were
moved to 9p-util(-linux) earlier in this series in the new
9p-util-darwin file.
