API's for iptable commands

[kadur.kiran at sawridgesystems.com]

Hi All,

iptables -t mangle -I FORWARD 1 -o em1 -d 10.180.190.221 -p tcp --sport
22 -j MARK --set-mark 102

I want to reproduce above iptables command programatically using API's.
But unable to find suitable documentation.
please suggest is there any approach to achieve the same.



Thanks,
