       MPI_Finalized  - Checks whether MPI_Finalize has completed.


C Syntax

       #include <mpi.h>
       int MPI_Finalized(int *flag)

Fortran Syntax

       INCLUDE 'mpif.h'
            LOGICAL   FLAG
            INTEGER   IERROR

C++ Syntax

       #include <mpi.h>
       bool MPI::Is_finalized()


       flag      True if MPI was finalized (logical).

       IERROR    Fortran only: Error status (integer).


       This routine returns "true" if MPI_Finalize has completed. You can call
       MPI_Finalized before MPI_Init and after MPI_Finalize.


       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.
