ctx

)

Reads a ArgObj structure from the AML byte stream.

A ArgObj is defined as ArgObj := Arg0Op | Arg1Op | Arg2Op | Arg3Op | Arg4Op | Arg5Op | Arg6Op where

• Arg0Op := 0x68,
• Arg1Op := 0x69,
• Arg2Op := 0x6A,
• Arg3Op := 0x6B,
• Arg4Op := 0x6C,
• Arg5Op := 0x6D and
• Arg6Op := 0x6E.

Note that if an ArgObj 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 ArgObj.
