\item[desc\_a] The communication descriptor.\\

\item[\bf On Return]
\item[bndel] The list of boundary elements on the calling process, in

\section*{Notes}
\begin{enumerate}
\item If there are no boundary elements (i.e., if the local part of
the connectivity graph is self-contained) the output vector is set
to \verb|NULL()|
\item Otherwise the size of \verb|bndel| will be exactly equal to the
number of boundary elements.
