I'd like programming a simple firewall.
This program should read a rules file, and every second check all the files /proc/[1-9][0-9]*/exe (executable file name) and /proc/[1-9][0-9]*/stat (process name). If that pair executable name/process appear in the rules file opening the relative ports. When the process disappears close them. I'll use iptables for this.
How can I list all the /proc/[1-9][0-9]*$ files in the most portable way?
correct me if im wrong but...
since this is for a unix-based system, then i assume any standard C functions will be very portable (within other unix-based systems that have /proc).
Yup, standard functions are portable across unixes.Quote:

In my BSD and Linux systems, both readdir(3) and opendir(3) calls are exist. And those are the functions that you wil use to work with directories!
(testing)
not have /proc system in my Free BSD
