I have an app which can open symlinks (not the thing the symlink

But when I drag a symlink to the icon of my app in the dock, -
(BOOL)application:(NSApplication *)theApplication openFile:(NSString
*)filename
will have filename = content of symlink (or alias).
And in case of a broken symlink nothing happens at all.
How can I open broken symlinks by dragging?
There's a good chance that you can't. It may be that Launch Services,
which is used by the Dock or the Finder to pass the open-document
request to your application in response to your drag operation, has
already resolved the symlink (or attempted to do so).
You could try installing a handler for the 'odoc' Apple Event to see
if you can override Cocoa's handling. I don't know if the framework
will let you do that.
You might have to build a Carbon application to test the possibility
at a low level, with the Cocoa framework removed from the equation.
If it's not possible there, it's almost certainly not possible in a
Cocoa app. Using the DTSCarbonShell sample code as a starting point,
it should be fairly easy to build such a test.
Cheers,
Ken
