17.2.91. MPI_Errhandler_set

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'

  • 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.

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.

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.
