python - Is there a way to get a meaningful mount point for st_dev on MacOS?

Question

Note this is a MacOS question not a Linux Question - They are different operating systems

I'd like to get a meaningful mount point out of python's os.stat("foo").st_dev. At the moment this is just a number and I can't find anywhere to cross reference it.

All my searches so far have come up with answers that work on Linux by interrogating /proc/... but /proc doesn't exist in MacOS so any such answer will not work.

Answer 1

I'm a Linux guy, but if I were not allowed to use /proc, I would search the /dev directory for an entry (i.e. filename) which has following stat data:

• st_mode indicates that it is a block device (helper: stat.S_ISBLK)
• st_rdev matches the given st_dev value
