#define INCL_GPISEGEDITING
 
BOOL GpiSetEditMode(hps, flEditMode)
HPS hps;            /* presentation-space handle */
LONG flEditMode;    /* editing mode              */
 
The GpiSetEditMode function sets the current editing mode. The editing mode
specifies whether new elements added to a retained segment are inserted into
the segment or whether they replace existing elements. The default editing
mode (set by the GpiCreatePS or GpiResetPS function) is insert.
 
Although the editing mode applies to retained segments only, the
GpiSetEditMode function can be used to change the editing mode at any time,
regardless of the drawing mode. However, the function cannot be used in an
element bracket.

            SEGEM_INSERT   Insert. The system inserts a new element after
                           the element pointed to by the element pointer.
                           The element pointer is updated to point to the
                           new element.
 
            SEGEM_REPLACE  Replace. The system replaces the element pointed
                           by the element pointer. The element pointer does
                           not change.
