Name

MPI_Win_set_errhandler - Attaches a new error handler to a window.

Syntax

C Syntax


#include <mpi.h>
int MPI_Win_set_errhandler(MPI_Win win, MPI_Errhandler errhandler)

Fortran Syntax


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

Fortran 2008 Syntax


USE mpi_f08
MPI_Win_set_errhandler(win, errhandler, ierror)
    TYPE(MPI_Win), INTENT(IN) :: win
    TYPE(MPI_Errhandler), INTENT(IN) :: errhandler
    INTEGER, OPTIONAL, INTENT(OUT) :: ierror

Input/Output Parameter

win
Window (handle).

Input Parameter

errhandler
New error handler for window (handle).

Output Parameter

IERROR
Fortran only: Error status (integer).

Description

MPI_Win_set_errhandler attaches a new error handler to a window. The error handler must be either a predefined error handler or an error handler created by a call to MPI_Win_create_errhandler.

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.
