ACAPI_Element_AttachObserver, notifyFlags

ACAPI_Element_AttachObserver takes an argument "notifyFlags".

I can't find any example addon (under the devkit folder) using this argument.

From the documentation:

"notifyFlags[in] Defines the behavior of the attached observer in certain database operations."

A bit vauge in my opinion.

Where can i find more informaition about these flags?

Whats the behavior and which database operations are they are talking about.

As I understand it you don't set this argument yourself. It is used by APIElementEventHandlerProc to tell which event is happening to the attached element.

A value is already assigned to it so you don't have to do anything

You can see it used in the notification manager exemple of the api > element_observer.cpp

I think you are confusing 'notifyFlags' with 'API_ElementDBEventID'
