mpi_finalized(3)
NAME
MPI_Finalized - Checks whether MPI_Finalize has completed.
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 (logical).
IERROR Fortran only: Error status (integer).
DESCRIPTION
This routine returns "true" if MPI_Finalize has completed. You can call
MPI_Finalized before MPI_Init and after MPI_Finalize.
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.
