Getting Hardware information

[praveenbk]

Hello,
Please help me in finding the Hardware ID of all PCI devices from /proc.

How can I read these datas from the /proc/bus/pci directory ussing C program?

Thanks & regards

Instead of reading data from /proc/bus/pci, u can use lspci or scanpci to get all the details related to ur hardware devices.

Depends also on what do you want to achieve.

Simply looking into those files you can with "cat /proc/bus/pci/devices". Everything there that is not a directory is a file and you can read it that way.

If you want to read the proc file systems from a C program, grep over the driver source tree. There is a lot of driver source files that write to or read from the proc file system.
