I'm working on FreeBSD support for a Python library called psutil for reading process information in a cross-platform fashion. Each platform-specific module is written in C, so the majority of the FreeBSD code is a C interface to various process information. I've been having some trouble working out how to get CPU user/kernel time for a given PID. I took a look at the source to top and ps but neither really helped since they don't seem to cover the info I was looking for (or I missed it).
I'm not sure if there's a better way to go about this but I've been looking at sysctl and the kinfo_proc struct - is there somewhere more appropriate to retrieve this information? If the kinfo_proc struct is the way to go, then do I want to use ki_runtime, ki_swtime or something else, and does that mean there's no distinction between user/kern time for a process? If anyone has code samples or recommended docs to get me pointed in the right direction that would be great.
