MPI_Comm_set_errhandler(3OpenMPI)                                          MPI_Comm_set_errhandler(3OpenMPI)



NAME
       MPI_Comm_set_errhandler  - Attaches a new error handler to a communicator.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Comm_set_errhandler(MPI_Comm comm,
            MPI_Errhandler errhandler)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_SET_ERRHANDLER(COMM, ERRHANDLER, IERROR)
            INTEGER   COMM, ERRHANDLER, IERROR


C++ Syntax
       #include <mpi.h>
       void MPI::Comm::Set_errhandler(const MPI::Errhandler& errhandler)


INPUT/OUTPUT PARAMETER
       comm      Communicator (handle).


OUTPUT PARAMETERS
       errhandler
                 New error handler for communicator (handle).

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Comm_set_errhandler  attaches  a  new  error handler to a communicator. The error handler must be
       either a predefined error handler or an error handler created by a  call  to  MPI_Comm_create_errhan-dler. MPI_Comm_create_errhandler.
       dler. This call is identical to MPI_Errhandler_set, the use of which is deprecated.


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.
