NAME
MPI_Win_call_errhandler - Passes the supplied error code to the error
handler assigned to a window
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Win_call_errhandler(MPI_Win win, int errorcode)
Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_WIN_CALL_ERRHANDLER(WIN, ERRORCODE, IERROR)
INTEGER WIN, ERRORCODE, IERROR
Fortran 2008 Syntax
USE mpi_f08
MPI_Win_call_errhandler(win, errorcode, ierror)
TYPE(MPI_Win), INTENT(IN) :: win
INTEGER, INTENT(IN) :: errorcode
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
C++ Syntax
#include <mpi.h>
void MPI::Win::Call_errhandler(int errorcode) const
INPUT PARAMETERS
win Window with error handler (handle).
errorcode MPI error code (integer).
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
This function invokes the error handler assigned to the window win with
the supplied error code errorcode. If the error handler was success-
fully called, the process is not aborted, and the error handler re-
turns, this function returns MPI_SUCCESS.
NOTES
Users should note that the default error handler is MPI_ERRORS_ARE_FA-
TAL. Thus, calling this function will abort the window processes if the
default error handler has not been changed for this 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.
See the MPI man page for a full list of MPI error codes.
