Input array of polygons to merge. |
Returns
Returns AcMap::EErrCode kOk if successful; otherwise, returns a different error code.

If one of the specified polygons shares no boundary with the others, this function fails. After a merge succeeds, the aPolygons[0] will reference the newly merged polygon. The other polygon references become invalid and are removed from aPolygons[].
