Find if mounted volume is Local or Network?

Subject: Find if mounted volume is Local or Network?

Given a path such as

  "/Volumes/SomeVolume/Hello.txt"

How can I determine whether or not SomeVolume is a Local or Network mount?

I have two kludgey solutions which utilize the FSRef of the given path:

Kludgey solution A: FSGetVolumeMountInfoSize() and FSGetVolumeMountInfo() return a -36 ioErr if the path is Local mount but return 0 noErr if it is Network. (Why?? -- Mac OS 10.5.8)

Kludgey solution B: FSCopyDiskIDForVolume() will return a "real" disk ID such as "disk0s3" or "disk1s2" if the path is Local but will return "Volumes/VolumeName" when the path is Network.

Solution B makes more sense, but is there a documented and reliable method?

Thanks,

Jerry Krinock
