MPI_Get_count - Returns the number of entries received in
       a message


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Get_count( status, datatype, count )
            MPI_Status   *status;
            MPI_Datatype datatype;
            int          *count;

       C++:

            #include <mpi.h>

            int Status::Get_count(
            const Datatype&   datatype) const

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER status(MPI_STATUS_SIZE), datatype, count, ierror

            CALL MPI_GET_COUNT(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 Standard.


DESCRIPTION

       The MPI_Get_count routine returns the number of entries
       received in a message.  This routine accepts the following
       parameters:

       status    Specifies the return status of the receive
                 operation (status).

       datatype  Specifies the data type of each receive buffer
                 element (handle).

       count     Returns the number of received elements.  If the
                 size of the data type is zero, this routine
                 returns a count of zero (integer).

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
