IODSubObject.pData (PROP)

PROPERTY pData : POINTER TO BYTE

Gets the pointer to the object value. Data is saved in Host Byte Order and can be directly accessed and modified.

Note

When changing an object manually, don’t forget to call IObjectDictionary.RaiseWriteObject before and IObjectDictionary.RaiseObjectChanged after modifiying the object. This is important to notify the stack and all other instances implementing IODCallback that an object change has happened. Otherwise there could be a stack missbehaviour regarding this object. But you can also call IObjectDictionary.WriteObject or IObjectDictionary.WriteObjectByAddress to modify an object’s value. In this case events are raised automatically.
