Since ICMCompressionSessionOptionsGetTypeID returns a CFTypeID, ICMCompressionSessionOptionsRef is apparently a CFType. As such, autorelease should work with it: http://www.cocoabuilder.com/archive/message/cocoa/2008/7/5/212046 I wish this were better documented; the Search Kit docs show autorelease being sent to an SKDocumentRef, also, and that's always made me nervous (I think I actually sent feedback on that one a long time ago). -- Adam _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
