SYNOPSIS
C:
#include <mpi.h>
int MPI_Get_elements ( status, datatype, elements )
MPI_Status *status;
MPI_Datatype datatype;
int *elements;
C++:
#include <mpi.h>
int Status::Get_elements(
const Datatype& datatype) const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER status(MPI_STATUS_SIZE), datatype, count, ierror
CALL MPI_GET_ELEMENTS(status, datatype, count, ierror)
STANDARDS
This release implements the MPI 1.2 standard, as documented by the MPI
Forum in the spring 1997 release of MPI: A Message Passing Interface
