Looks like sys/resource.h will define the structure if I do a -D_KERNEL. I may "cheat" and copy the structure def into my own code. (btw, what predefine by the comiler should I be useing for FreeBSD? while I am at it I _may_ try to add BSD sendfile support for the TCP_SENDFILE test) the sysctl(3) manpage doesn't mention cp_time as being part of the CTL_KERN set - probably a manpage oversight? > This provides a whole-system measurement, as taken from the kernel's > statclock routine.
