MPI_Win_get_errhandler(win, errhandler, ierror)
    TYPE(MPI_Win), INTENT(IN) :: win
    TYPE(MPI_Errhandler), INTENT(OUT) :: errhandler
    INTEGER, OPTIONAL, INTENT(OUT) :: ierror

Input Parameter

win
Window (handle).

Output Parameters

errhandler
Error handler currently associated with window (handle).
IERROR
Fortran only: Error status (integer).

Description

MPI_Win_get_errhandler retrieves the error handler currently associated with a 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.

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.
