How do I get a BSD device path string (eg: "/dev/rdisk3") that represents
the path to the device that holds a file for which I have a path string
(eg: "/Volumes/SOME_DATA_CD/A_SUB_FOLDER/THE_FILE.txt")?
I can get the dev_t number of the device using stat(), but I'm not sure
what to do with that number to get an actual path to the raw device.
... or maybe the stat() step is unnecessary altogether.
So (to sum up)...
How do I get a string like "/dev/rdisk3" starting with only the string "/Volumes/SOME_DATA_CD/A_SUB_FOLDER/THE_FILE.txt" ?
Thanks.
