Modify Owner of Object by LAPI

ImvecUser1_(Delete)_2148388

I tried to to modify the owner of object by updateversioninfo and here is the code status = LL_GetVersionInfo(session, parentVol, NodeID, 0, VersionInfo) status = LL_AssocSetInteger(VersionInfo, "Owner", newowner) status = LL_UpdateVersionInfo(session, parentVol, NodeID, 0, VersionInfo) the Owner of the object has not changed even it return status = LL_OK However, if i have use status = LL_GetObjectInfo(session, parentVol, NodeID, objectInfo) status = LL_AssocSetInteger(objectInfo, "UserID", newowner) status = LL_UpdateObjectInfo(session, parentVol, NodeID, objectInfo) the owner of the object changed succefully. So, should I use updateobjectinfo? Or is there any other method to modify the owner of the object? However, as stated in the dvelopment doc, the owner can not be changed by updateObjectInfo.
