only: Error status (integer).
MPI_Win_create_errhandler should
be, in C, a function of type MPI_Win_errhandler_fn, which is defined as
typedef void MPI_Win_errhandler_fn(MPI Win *, int *, ...);
The first argument is the window in use, the second is the error code to
be returned.
In Fortran, the user routine should be of the form:
SUBROUTINE WIN_ERRHANDLER_FN(WIN, ERROR_CODE, ...)
INTEGER WIN, ERROR_CODE
In C++, the user routine should be of the form:
typedef void MPI::Win::Errhandler_fn(MPI::Win &, int *, ...);
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.
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.
