Vince,
I got an idea that will enable to do you want. Try it.
Before your C-style function to be called back, declare static
reference to
your object as below.
static id myObject;
And set it up in initialization or in 'awakeFromNib:'...
myObject = self;
Now, your call back function is able to send any message to the object.

I'm a Object C newbie and hope someone here can help. I need to pass a
function call-back to a C- style function from one of my objects. I
have declared the call-back function before the @implementation MyObj.
The problem I'm having is accessing my object from within the call-back
function, which doesn't seem to know about my object. I want the
callback to send a setter message to my object. I'd rather be able to
pass a call-back that was a method of my object instead. Is there a way
to pass a Obj C style message as a function* in place of the C-style
function???
Thanks in advance
