PK_ERROR_code_t     PK_SESSION_ask_swept_spun_surfs
(
--- received arguments ---

--- returned arguments ---
PK_LOGICAL_t *const whether --- whether swept/spun surfaces enabled
)


This function returns whether topological sweep and spin functions are
allowed to produce swept and spun surfaces.


If whether is returned as PK_LOGICAL_true then the functions:

    PK_BODY_sweep
    PK_BODY_spin
    PK_FACE_sweep
    PK_FACE_spin

may produce surfaces of classes PK_CLASS_swept and PK_CLASS_spun.

If whether is returned as PK_LOGICAL_false then these functions will create
surfaces of class PK_CLASS_bsurf.
