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 another).

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++ functions 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.
