hi

The "ps" command shows the command line arguments of running processes:

$ /bin/ps -o pid,args -e
....
26031 pico /tmp/crontab2KaG1Y
596 /usr/lib/sendmail -bd -q15m
9955 xterm -n 1 -sb -sl 800 -g 80+70+70
2627 /usr/sbin/snmpd -Lsd -Lf /dev/null -p /var/run/snmpd -a 1691
....

I need to write a C program to get the command line arguments of a particular process id, but do not want to rely on:

system("/bin/ps -o pid,args -e");
--or--
popen("/bin/ps -o pid,args -e", "r");

On Solaris, the command line arguments of a running process are stored at: /proc/<pid>/psinfo
On Linux, the command line arguments of a running process are stored at: /proc/<pid>/cmdline

These two files are not text files, so I'm not sure how to read the contents.

Where can I find example C code to read the contents of the "psinfo" and "cmdline" files?

Thanks
