  void MPI::Win::Get_name(char* win_name, int& resultlen) const

win

Window whose name is to be returned (handle).

win_name

the name 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.
