Portable, no /proc... ? It could be tough to do this generically. Why not look at unixtop, which tries to be portable?: http://sourceforge.net/projects/unixtop/files/ I think on FreeBSD it resorts to using kvm(3). You could just call that directly. Also, coming soon on FreeBSD, there will be libprocstat, which aims at making this easier: http://svn.freebsd.org/viewvc/base/projects/libprocstat/ stas@ is working on that. This kind of question is best suited for freebsd-hackers@ .
