)

Reads a LocalObj structure from the AML byte stream.

A LocalObj is defined as LocalObj := Local0Op | Local1Op | Local2Op | Local3Op | Local4Op | Local5Op | Local6Op | Local7Op where

• Local0Op := 0x60,
• Local1Op := 0x61,
• Local2Op := 0x62,
• Local3Op := 0x63,
• Local4Op := 0x64,
• Local5Op := 0x65,
• Local6Op := 0x66 and
• Local7Op := 0x67.

Note that if a LocalObj is storing a ObjectRefernce it will be Automatically dereferenced, so in such a situation out will point to the actual object and not an ObjectReference in the LocalObj.
