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


INCLUDE ’mpif.h’
MPI_WIN_CALL_ERRHANDLER(WIN, ERRORCODE, IERROR)
    INTEGER    WIN, ERRORCODE, 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 successfully called, the process is not aborted, and the error handler returns, this function returns MPI_SUCCESS.

Notes

Users should note that the default error handler is MPI_ERRORS_ARE_FATAL. 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++ 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.

See the MPI man page for a full list of MPI error codes.
