Reading and Parsing Data from /proc/net/dev

[sumitv]

Hi,

I am designing a web page for my product to display network interface information. My product is linux based having ethernet(eth0) and wireless lan(eth1) interfaces.

When I cat /proc/net/dev, I see following information:
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
lo: 405513 7108 0 0 0 0 0 0 405513 7108 0 0 0 0 0 0
eth0: 165194 1594 2 0 2 0 0 681 607273 809 0 0 0 0 0 0
eth1: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Sorry for this data distortion. Now I want to read packets received, sent, errors, dropped packets count for both the interfaces and display it on my web page. I have a C program as my web page backend. What is the best way to read and parse this data? Are there ioctls available for this?

Regards,
Sumit

Oh.. this is the same what I want.. both have the same requirement...
do u have any ioctls or some c-fucntions to get the list interfaces and their details like ipaddress, gateway, route etc...

This is the ioctl that I used to get hardware address (mac address) of ethernet chip.

ioctl(s, SIOCGIFHWADDR, &buffer);

I am still finding ioctl to read number of packets received, dropped, transmitted, errors etc.
You can get ioctls for ipaddress, gateway, route etc in your chip/module specific ioctl documentation. The vendor/manufacturer must have provided you with this documentation.

Let me know if you find a suitable way to parse /proc/net/dev.
