 I think Manuel wanted to know what particular information you need to get,
 i.e. why are you looking into this kinfo_proc at all.
 
 Perhaps there is other suitable interface, or some set of headers which
 need to be included. Groweling through kernel internal structures is
 usually bad sign, and it's almost always non-portable, and tends to break
 between OS versions. We provide binary-safe interfaces in order to make it
 simpler to keep the apps working.
 
 So what is the purpose of the code you are trying to get to compile and
 run, what kind of information do you need to get, why the standard POSIX
 interfaces are not sufficient?
