NAME
MPI_Finalized - Checks whether MPI has been finalized
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Finalized(int *flag)
Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_FINALIZED(FLAG, IERROR)
LOGICAL FLAG
INTEGER IERROR
Fortran 2008 Syntax
USE mpi_f08
MPI_Finalized(flag, ierror)
LOGICAL, INTENT(OUT) :: flag
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
C++ Syntax
#include <mpi.h>
bool MPI::Is_finalized()
OUTPUT PARAMETER
flag True if MPI was finalized, and false otherwise (logical).
IERROR Fortran only: Error status (integer).
DESCRIPTION
This routine may be used to determine whether MPI has been finalized.
It is one of a small number of routines that may be called before MPI
is initialized and after MPI has been finalized (MPI_Initialized is an-
other).
ERRORS
Almost all MPI routines return an error value; C routines as the value
of the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set to
MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI::Exception object.
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with
MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN
may be used to cause error values to be returned. Note that MPI does
not guarantee that an MPI program can continue past an error.
