MPI_Win_get_errhandler(3OpenMPI)MPI_Win_get_errhandler(3OpenMPI)NAME
MPI_Win_get_errhandler - Retrieves the error handler currently associated with a window.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Win_get_errhandler(MPI_Win win, MPI_Errhandler *errhandler)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_WIN_GET_ERRHANDLER(WIN, ERRHANDLER, IERROR)
INTEGER WIN, ERRHANDLER, IERROR
C++ Syntax
#include <mpi.h>
MPI::Errhandler MPI::Win::Get_errhandler() const
INPUT PARAMETER
win Window (handle).
OUTPUT PARAMETERS
errhandler
Error handler currently associated with window (handle).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Win_get_errhandler retrieves the error handler currently associated with a window.
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.

MPI_Errhandler_free - Frees an MPI-style error handler.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Errhandler_free(MPI_Errhandler *errhandler)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_ERRHANDLER_FREE(ERRHANDLER, IERROR)
INTEGER ERRHANDLER, IERROR
C++ Syntax
#include <mpi.h>
void Errhandler::Free()
INPUT PARAMETER
errhandler
MPI error handler (handle). Set to MPI_ERRHANDLER_NULL on exit.
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
Marks the error handler associated with errhandler for deallocation and sets errhandler to MPI_ERRHANDLER_NULL. The error handler will be
deallocated after all communicators associated with it have been deallocated.

Hi all,
I write a simple MPI program to send a text message to another process. The code is below.
(test.c)
#include "mpi.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char* argv) {
int dest, noProcesses, processId;
MPI_Status status;

In setting up an 8e on 5.0.5 I couldn't find a memory window that worked using mpi (3 versions).
The memory search program (DOS based) indicated E800 was available but mpi only listed E000.
I resolved my immediate problem by changing the window value in /etc/conf/pack.d/pcxx/space.c prior to... (2 Replies)
