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.
