Inside Macintosh: Interapplication Communication /
Chapter 2 - Edition Manager / Subscribing to Non-Edition Files

Opening and Closing Editions

Each time the Edition Manager opens or closes an edition container, it calls the current edition opener procedure and passes it an opener verb and a parameter block.

Your opener must be careful when closing documents since a document may already have been opened by another application. Be sure to use the Open/Deny modes whenever possible. Do not close a document if it was already open when your application opened it.
