In Yosemite (10.10), Carbon's PBGetCatalogInfoBulk and directory enumerators created with CoreFoundation's CFURLEnumerator (it's in CFURLEnumerator.h, not CFURL.h) both use getattrlistbulk() instead of readdir() or getdirentriesattr(). Foundation API like- [NSFileManager contentsOfDirectoryAtURL:includingPropertiesForKeys:options:error:] are layered upon CFURLEnumerator so they are using getattrlistbulk(), too.

For the most part, all of Apple's code has switched from getdirentriesattr() to getattrlistbulk().

Thanks for the clarification, Eric.

Do any of the higher level APIs also make use of this call, or do I have to use this call to take advantage of its functionality?

I guess that NSURL's contentsOfDirectoryAtURL:includingPropertiesForKeys:options:error: makes use of it.

I can't find a CFURL equivalent for this bulk call, though. Has it been omitted or am I just looking at the wrong docs?

And what about PBGetCatalogInfoBulk and FSOpenIterator with related functions?
