Is there a way to open file by known inode

Question

I get an inode for some logging file like '/tmp/logging'
and I want to open it via inode, NOT path.
How to do it?

In general you cannot do this from user-space because the system routines accept a path as an argument.

Take a look at this post.

Ah, nice find — much better than my link. OP, give this (wo)man an accept! – David Wolever Mar 25 '12 at 06:44

Short of a brute-force search of the filesystem for the inode (ex, find / -inum $X), you can't.

IIRC not every inode needs to be listed in a directory – 6502 Mar 25 '12 at 06:42
