Thank you for your response.
I attempted to compile procstat but procstat.h seems to be missing in tgz.
Yuri,
Indeed -- looks like I forgot to p4 add on my development box. I've updated
the tarball to now include procstat.h. If there are any other problems, do
let me know.

I am looking for functionality similar to Linux's /proc/<PID>/fd/<FD>. I
need to know what is the file name of an open file descriptor.
/proc/<PID>/fd is missing on FreeBSD.
There's something called 'fdescfs'. In /dev/fd/ it shows the list of file
descriptors. But they don't seem to be symbolic links to open files. And
also it only shows FDs of the current process.
So why there's no /proc/<PID>/fd in FreeBSD? And how do I work around this?
Or should I just invest time and write a kernel patch implementing
/proc/<PID>/fd/?
You can give these patches a try:
http://www.watson.org/~robert/freebsd/20071112-procstat.tgz
They reflect a work-in-progress procstat(1) tool, which inspects process
state
in various ways. They are developed against 8-CURRENT, but likely still
apply
fairly easily to 7-STABLE. They suffer various deficiencies, such as relying
on the name cache in-kernel to generate file paths for mapped files and open
file descriptors, so don't currently work with devfs nodes (for example).
However, they may do what you need. Any feedback would be most welcome.
