MPI_Errhandler_set(3) Open MPI MPI_Errhandler_set(3)NAMEMPI_Errhandler_set - Sets the error handler for a communicator -- use
of this routine is deprecated.
SYNTAXC Syntax
#include <mpi.h>
int MPI_Errhandler_set(MPI_Comm comm, MPI_Errhandler errhandler)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_ERRHANDLER_SET(COMM, ERRHANDLER, IERROR)
INTEGER COMM, ERRHANDLER, IERROR
INPUT PARAMETERS
comm Communicator to set the error handler for (handle).
errhandler
New MPI error handler for communicator (handle).
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
Note that use of this routine is deprecated as of MPI-2. Please use
MPI_Comm_set_errhandler instead.
This deprecated routine is not available in C++.
Associates the new error handler errhandler with communicator comm at
the calling process. Note that an error handler is always associated
with the communicator.
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++ func‐
tions 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.
