MPI_Win_set_errhandler - Attaches a new error handler to a window.

17.2.453.1. SYNTAX

17.2.453.1.1. C Syntax

#include <mpi.h>

int MPI_Win_set_errhandler(MPI_Win win, MPI_Errhandler errhandler)

17.2.453.1.2. Fortran Syntax

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

17.2.453.1.3. 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

17.2.453.2. INPUT/OUTPUT PARAMETER

  • win: Window (handle).

17.2.453.3. INPUT PARAMETER

  • errhandler: New error handler for window (handle).

17.2.453.4. OUTPUT PARAMETER

  • IERROR: Fortran only: Error status (integer).

17.2.453.5. 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.

17.2.453.6. 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.
