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

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++ 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.
