A Cocoa means to detect SysPref 'Enable access for assistive devices"

Folks;

Is there a straight Cocoa means to detect the System Preferences/
Universal Access setting for 'Enable access for assistive devices'?

I've found plenty of references on using Applescript to detect this 
setting.
The Cocoa Assistive API seems pretty extensive but I can't glean a way 
to just determine this setting using Cocoa...

I understand the potential 'admin' aspects of the setting.
All I want is a means to know what the current setting is.

Any links or code snippets appreciated!
