19 Continuation Marks

A mark can be attached to the current continuation frame using scheme_set_cont_mark. To force the creation of a new frame (e.g., during a nested function call within your function), use scheme_push_continuation_frame, and then remove the frame with scheme_pop_continuation_frame.
