IBACnetPersistence.UpdateProperties (METH) ¶ METHOD UpdateProperties : CmpBACnet.IEC_BACNET_STATUS Updates the object initialization data with the persistent data (if present). InOut: Scope Name Type Comment Return UpdateProperties CmpBACnet.IEC_BACNET_STATUS Input devInstance CmpBACnet.IEC_BACNET_DWORD The device instance for which objects the update should be done. objID CmpBACnet.IEC_BACNET_OBJECT_ID The object identifier for which the update should be done. Inout propList POINTER TO CmpBACnet.IEC_BACNET_PROPERTY_INSTANCE The pointer to the array with the property declarations for the object initialization. propCount CmpBACnet.IEC_BACNET_UNSIGNED The number of entries in the array with properties. Output pBuffer POINTER TO BYTE This pointer is used to store the allocated buffer pointer which contains the loaded data which are needed for object construction. The application has to free this buffer after object construction.

IBACnetPersistence.FreePersistenceInfos (METH) ¶ METHOD FreePersistenceInfos : CmpBACnet.IEC_BACNET_STATUS Deallocate buffer allocated from IBACnetPersistence.GetPersistenceInfos . InOut: Scope Name Type Comment Return FreePersistenceInfos CmpBACnet.IEC_BACNET_STATUS Input pInfo POINTER TO BACnetPersistenceInfo Array of information about stored objects.
