I need a reliable method of detecting a proc filesystem mounted under an directory (not necessarily /proc) which would work under Linux, *BSD and Solaris (and eventually other UNIX-like systems).
This is more like a programming issue, but i'm only interested in a method, a system call (even platform specific) or something, but *reliable*. It also needs to detect a procfs if mounted via --bind (on linux).
The methods i've thought of are: parsing /etc/mtab and using statfs(), both of them not so reliable..
Does anybody else know other methods?
