--- MPID entry point for MPI{\tt \char`\_}Recv 
\subhead{Synopsis}
\startvb\begin{verbatim}
int MPID_Recv( void *buf, int count, MPI_Datatype datatype,
               int source, int tag, MPID_Comm *comm, int context_offset,
               MPI_Status *status, MPID_Request **request )

\end{verbatim}
\endvb

\subhead{Notes}
The only difference between this and {\tt MPI{\tt \char`\_}Recv} is that the basic
error checks (e.g., valid communicator, datatype, source, and tag)
have been made, the MPI opaque objects have been replaced by
MPID objects, a context id offset is provided in addition to the
communicator, and a request may be returned.  The context offset is added
to the context of the communicator to get the context it used by the message.
As in {\tt MPID{\tt \char`\_}Send}, the request is returned only if the operation did not
complete.  Conversely, the status object is populated with valid information
only if the operation completed.
