I had difficulties to setup MSG port and IO port for the program I did...
Now that these functions are obsolete, I'd likt to update them to new methods...
In SDK 53.30 Autodocs exec.doc, these functions are always in

Does someone can give me a clue on how I can replace these functions :
- CreateMsgPort
- DeleteMsgPort
- CreateIORequest
- DeleteIORequest
Thank you.
