MPI_Errhandler_get - Gets the error handler for a communicator
-- use of this routine is deprecated.
#include <mpi.h>
int MPI_Errhandler_get(MPI_Comm comm, MPI_Errhandler *errhandler)
INCLUDE ’mpif.h’
MPI_ERRHANDLER_GET(COMM, ERRHANDLER, IERROR)
INTEGER COMM, ERRHANDLER, IERROR
- comm
- Communicator to get the error handler from (handle).
- errhandler
- MPI error handler currently associated with
communicator (handle).
- IERROR
- Fortran only: Error status (integer).
Note
that use of this routine is deprecated as of MPI-2. Please use MPI_Comm_get_errhandler
instead.
This deprecated routine is not available in C++.
Returns in errhandler
(a handle to) the error handler that is currently associated with communicator
comm.
Example: A library function may register at its entry point the current
error handler for a communicator, set its own private error handler for
this communicator, and restore before exiting the previous error handler.
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.
