NAME

       MPI_Finalized  - Checks whether MPI has been finalized

SYNTAX

C Syntax

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

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_FINALIZED(FLAG, IERROR)
            LOGICAL   FLAG
            INTEGER   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.
