If the port uses a script to extract the data, a tool like lsof may do the trick. However, I'm not sure there are any native APIs to query that data "as shipped" in 6.3. Once I've had some reasonable feedback on procstat(1), I'll merge it into CVS and start it on the MFC route, but 6.3 is almost certainly too soon for it to ship as part of that release. I don't know if there will be a 6.4 or not, but I would anticipate procstat(1) appearing in 7.1, and 6-STABLE if there are requests. procstat(1) mostly relies on existing sysctls, and adds two new ones for the purposes of exporting the file descriptor and VM information only, so it is a fairly straight forward MFC.
