Hi,                                                                                                                                                                                            
                                                                                                                                                                                               
pfind and friends looks like kernel only function. I can suggest you to explore                                                                                                                
the sysctl(3) way to recover the kern.proc structures. There are fexw examples                                                                                                                 
on the internet, you can check a code I wrote few years ago to recover the                                                                                                                     
battery state in my laptop using sysctl ; hope this help.
