In BSD /proc/<a pid> contains 

[marcov at dragon ~]$ ls /proc/44539
cmdline ctl     etype   file    map     rlimit  status
[marcov at dragon ~]$

but afaik BSDs can turn /proc off, and this is commonly done so on servers.

/proc is only a SysV compatibility feature there,
most BSD-own tools work via other interfaces (like sysctl(3))

Turning it off is getting rarer though (probably linux converging).
