Function Group  Overview                          Up Next Previous
────────────────────────────────────────────────────────────────────────────
 
#define INCL_GPISEGEDITING
 
BOOL GpiSetElementPointerAtLabel(hps, idLabel)
HPS hps;         /* presentation-space handle */
LONG idLabel;    /* label identifier          */
 
The GpiSetElementPointerAtLabel function moves the element pointer to the
element containing the specified label. The function starts the search at
the next element after the current element-pointer position. If the function
does not find the label before reaching the end of the segment, the function
leaves the element pointer unchanged and returns an error.
 
The function can be used only in an open segment and only with DM_RETAIN
drawing mode. The function cannot be used in an element bracket.
