objective-c question: get selector by ascii name

[Rick Riolo]

Hi,
I would like to get a SELector by ascii name,
and I thought (on reading the Obj-C book from NextStep,
Chapter 2, "Selectors", page 65) that I could do:

    SEL mySetXXX = sel_getUid("setXXX");

(That's the cap/spelling I see in my copy of the book.)
But when I compile this, it warns me that it doesn't
have a prototype for sel_getUid() and when it links
it can't find it.

Is that not available in gcc, or is there some other name
for it?  Or do I need to link in some special lib?

thanks for the info?
