Equivalent for Windows messages (EM_LINEFROMCHAR/EM_LINEINDEX) in OSX/Cocoa

Question

ALL,

Is there an equivalent for EM_LINEFROMCHAR/EM_LINEINDEX Windows notification in OSX/Cocoa? I couldn't find anything looking here.

Basically I'm looking to give a position and receive (x,y) coordinate inside the view.

See - (CGPoint)locationForGlyphAtIndex:(NSUInteger)glyphIndex; of NSLayoutManager.

You may wanna read on the relation between NSTextView, NSTextStorage and NSLayoutManager.
