I am trying to find out the pathname of a disk file from its vnode in the
kernel's memory (What I have done is to go through uf_ofile of the process's
user area which then points to the file structure).
I understand that v_data points to "private data" which is the inode structure
if the file is a disk file. Can someone tell me how I can find out the file's
name (the inode number and filesystem would be good enough)? How can I tell
that the vnode is referencing a disk file?

Thanks for any help

There is a tool called lsof (list of open files) out there. Look at
the code, it is very comprehensive. I don't know it's home ftp server,
we have it at ftp.novell.de:/pub/unixware/usle/sources.
