HIGEAR hIGear; /* HIGEAR handle of image */ AT_ERRCOUNT nErrcount; /* tally of IG errors on */ /* stack */ ART_MARK_INDEX hMarkIndex; /* index to current mark */ ART_MARK_ATTRIBUTES ma; /* structures for */ /* attributes of current */ /* mark */ BOOL fEnable; /* whether access for */ /* editing */ /* is granted to the mark */ nErrcount = ART_mark_query(hIGear, hMarkIndex, &ma); if (ma.dwType == 10) { /* if mark is an attach-a-note */ nErrcount = ART_mark_access_is_granted(hIGear, hMarkIndex, fEnable); if (fEnable == TRUE) { /*if access is granted, deny the access */ nErrcount = ART_mark_access (hIGear, hMarkIndex, FALSE); /*deny access to this mark */ } } |

Remarks:
Access to a mark includes the ability to edit it. When fEnable is set to TRUE, the mark can be edited. When fAccess is set to FALSE, the mark editing is disabled.
An error is set if any of the following conditions are met:
- hIGear does not reference a valid ImageGear handle.
- There are no marks with a matching index block.
