--- Description of the error handler structure 
\subhead{Synopsis}
\startvb\begin{verbatim}
typedef struct {
  int                handle;
  volatile int       ref_count;
  MPID_Lang_t        language;
  MPID_Object_kind   kind;
  MPID_Errhandler_fn errfn;
  /* Other, device-specific information */
} MPID_Errhandler;

\end{verbatim}
\endvb

\subhead{Notes}
Device-specific information may indicate whether the error handler is active;
this can help prevent infinite recursion in error handlers caused by
user-error without requiring the user to be as careful.  We might want to
make this part of the interface so that the {\tt MPI{\tt \char`\_}xxx{\tt \char`\_}call{\tt \char`\_}errhandler
}routines would check.
\par
It is useful to have a way to indicate that the errhandler is no longer
valid, to help catch the case where the user has freed the errhandler but
is still using a copy of the {\tt MPI{\tt \char`\_}Errhandler} value.  We may want to
define the {\tt id} value for deleted errhandlers.
