Re: Forwarding to Super

Thanks for the reply. Indeed I want to use that function, but you have to pass arguments to it somehow, and that is what the apply function does. Check out http://gcc.gnu.org/onlinedocs/gcc-3.4.0/gcc/Constructing- Calls.html#Constructing Calls

I need to invoke an NSInvocation with the target as the super object of a given object. That is, I need to invoke the super class's implementation.

Can I somehow access the argumentFrame of NSInvocation to get the arguments for the __builtin_apply() function?
I tried doing this by getting the Ivar of the variable, but I only got a bad access when I tried to apply the offset, so
perhaps I am not doing it correctly.

Must I recreate the argumentFrame by parsing the arguments by hand?
Or is there a higher-level way to do it?

Thanks.

I don't know what this __builtin_apply() function is, but the Objective-C runtime API has a function, objc_msgSendSuper, which is surely what you want. See <http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/ 9objc_runtime_reference/chapter_5_section_1.html#//apple_ref/doc/uid/ 20001426>.
