Need network adapter information in a c program


Platform : redhat ent linux 4
i am working on a c program in which i need some details which are listed below:

> network Adapter Description (name of the hardware).
> the link speed or the bandwidth of the connection.
> the current bandwidth under usage.

can anyone tell me where i can get a library that helps in getting these system information. i've already tried libgtop and libpcap but they dont provide the above mentioned information.also i am not allowed to write anything to the disk.

Hello.

Take a look at `lspci (8)' and `/proc/bus/pci/devices'. Try `lspci -vv'. Maybe the source code of lspci will be helpful.

Hope, this helps.
