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

USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_WIN_GET_ERRHANDLER(WIN, ERRHANDLER, IERROR)

INTEGER WIN, ERRHANDLER, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_Win_get_errhandler(win, errhandler, ierror)

	TYPE(MPI_Win), INTENT(IN) :: win
	TYPE(MPI_Errhandler), INTENT(OUT) :: errhandler
	INTEGER, OPTIONAL, INTENT(OUT) :: ierror

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++ 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.
