The functions CFURLGetFSRef and CFURLCreateFromFSRef have deprecation warnings that say "not supported". That confuses me, because when I see "deprecated" I think "it may stop working at some point in the future", and when I see "not supported" I think "it doesn't work now". Which is it?
Where do you get each ?
I think both are correct, and not supported (in a certain OS version) is just a deprecated that has come to an end.
In any case, you should not use anymore.
Not sure what you mean by "where do you get each". For example, using CFURLCreateFromFSRef produces:
warning: 'CFURLCreateFromFSRef' is deprecated: first deprecated in macOS 10.9 - Not supported [-Wdeprecated-declarations]
FSRef is also deprecated (and comes with the warning that it's not on friendly terms with APFS), so the question is: where are you getting your FSRef?
Yes, I know FSRef is deprecated. I have some legacy code with FSRef all over the place, and it's hard to budget a man-month to fix something that's not actually causing problems for users. To give just one example of where an FSRef might come from, some legacy data might contain an old-fashioned Alias handle, so I need to call FSResolveAlias.
