void Errhandler::Free()
- errhandler
- MPI error handler (handle). Set to MPI_ERRHANDLER_NULL
on exit.
- IERROR
- Fortran only: Error status (integer).
Marks
the error handler associated with errhandler for deallocation and sets
errhandler to MPI_ERRHANDLER_NULL. The error handler will be deallocated
after all communicators associated with it have been deallocated.
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.
