NAME¶
MPI_Errhandler_set - Sets the error handler for a communicator -- use of
this routine is deprecated.
SYNTAX¶
C 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
- 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++ 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.
