Pop-up NSMenu without NSPopUpButton

How do I make an NSMenu act as a pop-up menu without the use of 
NSPopUpButton? I see there are class methods to make it pop up as a 
contextual menu, but I need it to pop up as a pop-up menu like 
NSPopUpButton magically does, so that one item in the menu can be pre-
selected.

I've searched the archives, and have already tried calling 
_NSGetCarbonMenu() for use with PopUpMenuSelect(), but the function is 
always returning NULL, and even if this did work and didn't use 
undocumented methods, it still won't work in 64-bit.
