bool MPI::Is_finalized()
- flag
- True if MPI was finalized, and false otherwise (logical).
- IERROR
- Fortran only: Error status (integer).
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).
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.
