Getting info about network devices

[Krishnendu Sadhukhan]

Well, I am coding in C, so ifconfig won't be that convenient. I am rather looking for some kind of system data file, like /etc/path_to_inst in Solaris.

Does RedHat provide this kind of data file so that programs can make use of them easily ?
