Reading PCI IDs ?

Hi,

how can one read the PCI ID of the chipset built into a computer?
I know lspci can do it with "-n" and the first line contains the PCI ID of the chipset:

Code:

---

$ lspci -n
00:00.0 0600: 8086:2a00 (rev 03)
[...]

---

The bold marked info is what I'm looking for. I haven't dealt with such things in C before and the lspci source code wasn't especially useful for me because I just wasn't able to understand it... (I'm not a professional coder, it's just a hobby and I'm not doing this for so long)

So if anyone can tell me where exactly in the lspci source code I will have to look or has a simpler piece of code it would be great if he'd share it with me :)

Try looking at:

/proc/pci
/proc/bus/pci/devices
/proc/bus/pci/*

lspci reads the files under /sys/bus/pci/devices (you can easily find this out without browsing it's source using the command #strace lspci 2>&1 | less)
