--- Implement a get operation where the source and  destination datatypes are (roughly) the same 
\subhead{Synopsis}
\startvb\begin{verbatim}
int MPID_Get_sametype( void *origin_buf, int n, MPID_Datatype *dtype,
                      MPI_Aint target_offset, int target_rank, MPID_Comm *comm,
                      volatile int *local_flag, MPI_Aint target_flag )

\end{verbatim}
\endvb

\startarg{buf }{Pointer to local memory to be to hold fetched data
}
\startarg{n   }{Count of datatype to move
}
\startarg{dtype }{Datatype describing both the source and destination datatype. 
See notes.
}
\startarg{target{\tt \char`\_}offset }{Location of destination 
}
\startarg{target{\tt \char`\_}rank }{Rank of the destination process in the communicator
}
\startarg{comm }{Communicator
}
\startarg{local{\tt \char`\_}flag }{Address of a flag to be set when this call is locally complete.
}
\startarg{target{\tt \char`\_}flag }{This is an id of a flag at the target process.  This value
must have been specified by the target process in a previous communication
(either with {\tt MPID{\tt \char`\_}Put{\tt \char`\_}contig} or {\tt MPID{\tt \char`\_}Rhcv}).  A value of {\tt 0} indicates no
target completion flag.
Notes:
This routine allows the efficient implementation of strided copies, where
both the origin and the target have the same strides.
