MPI_Finalized

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.
