SYNTAX
C Syntax
#include <mpi.h>
int MPI_Win_set_errhandler(MPI_Win win, MPI_Errhandler errhandler)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_WIN_SET_ERRHANDLER(WIN, ERRHANDLER, IERROR)
INTEGER WIN, ERRHANDLER, IERROR
C++ Syntax
#include <mpi.h>
void MPI::Win::Set_errhandler(const MPI::Errhandler& errhandler)
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. 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.
