void MPI::Win::Get_name(char* win_name, int& resultlen) const
- win
- Window whose name is to be returned (handle).
- win_name
- the Tame previously stored on the window, or an empty
string if no such name exists (string).
- resultlen
- Length of returned name
(integer).
- IERROR
- Fortran only: Error status (integer).
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.
