MPI_FINALIZED(3)MPI_FINALIZED(3)NAMEMPI_Finalized - Determines whether MPI has finalized
SYNOPSIS
C:
#include <mpi.h>
MPI_FINALIZED(flag)
int MPI_Finalized(int *flag)
Fortran:
INCLUDE "mpif.h" (or USE MPI)
LOGICAL flag
INTEGER ierror
CALL MPI_FINALIZED(flag, ierror)
C++:
bool MPI::Is_finalized()
This routine returns true if MPI_Finalize has completed.
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_Finalized routine determines whether MPI has finalized. This
routine is part of the MPI-2 standard and is provided for MPI layered
libraries to function properly.
MPI is "active" and it is thus safe to call MPI functions if MPI_Init has
completed and MPI_Finalize has not completed. For example, MPI is
"active" in callback functions that are invoked during MPI_Finalize. If a
library has no other way of knowing whether MPI is active, it can use
MPI_Initialized and MPI_Finalized to determine this. It is legal to call
MPI_Finalized before MPI_Init and after MPI_Finalize. Once MPI has been
finalized, it is no longer active and cannot be restarted.
MPI_Finalized accepts the following arguments:
flag Returns true if MPI was finalized (logical).

ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h
file (integer).
