Just some of the private CoreDock functions, which are used by the Dock prefpane. Framework: /System/Library/Frameworks/ApplicationServices.framework/Frameworks/HIServices.framework

typedef enum { kCoreDockOrientationTop = 1, kCoreDockOrientationBottom = 2, kCoreDockOrientationLeft = 3, kCoreDockOrientationRight = 4 } CoreDockOrientation;

extern Boolean CoreDockGetAutoHideEnabled(void); extern void CoreDockSetAutoHideEnabled(Boolean flag);

To be notified of changes to the Dock (by Dock.app and SystemPreferences), register your class as observer to the distributed notification “com.apple.dock.prefchanged” (using NSDistributedNotificationCenter).

TonyArnold says: there is a more up-to-date version, plus some new calls at http://code.google.com/p/undocumented-goodness/source/browse/trunk/CoreDock/CoreDockPrivate.h
