17.2.159. MPI_Finalized

MPI_Finalized - Checks whether MPI has been finalized

17.2.159.1. Syntax

17.2.159.1.1. C Syntax

#include <mpi.h>

int MPI_Finalized(int *flag)

17.2.159.1.2. Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'

MPI_FINALIZED(FLAG, IERROR)
    LOGICAL FLAG
    INTEGER IERROR

17.2.159.1.3. Fortran 2008 Syntax

USE mpi_f08

MPI_Finalized(flag, ierror)
    LOGICAL, INTENT(OUT) :: flag
    INTEGER, OPTIONAL, INTENT(OUT) :: ierror

17.2.159.2. Output Parameter

  • flag : True if MPI was finalized, and false otherwise (logical).

  • IERROR : Fortran only: Error status (integer).

17.2.159.3. 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).

17.2.159.4. Errors

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. 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.
