Consults the binding tables to return the application that would be used to open the folderitem if it were double-clicked in the Finder. This application will be the user-specified override if appropriate or the default otherwise. If no application is known to LaunchServices suitable for opening this item, nil (kLSApplicationNotFoundErr) will be returned.

Constants you can use for the role parameter:
kLSRolesNone = 1no claim is made about support for this type/scheme
kLSRolesViewer= 2claim to be able to view this type/scheme
kLSRolesEditor= 4claim to be able to edit this type/scheme

Upgraded in version 19.5 to use CFURL instead of FSRef APIs.
