does anyone know where there is one for the iPhone? I have searched the docs, and am having all sorts of trouble, I thought this would be a gimme

I doubt there is a built-in function for these that takes 3 arguments. The standard ones all take two. Of course min(x,y,x) = min(min(x,y),min(x,z))...

Yep, that would work too :)

Or just write a custom function to do the comparisons.

MIN and MAX are defined in NSObjCRuntime.h.

Start there.

m = a < b ? ( a < c ? a : c ) : ( b < c ? b : c ) ;

If you are using it frequently, set up a #define. Lace with plenty of parentheses, though.
