reading wifi signal level with C

[occam25]

Hi!
I am programming in C on Linux and I want my program to be able to read the signal level of the wifi network. Are there any library or api to do that? How can I get the wireless card information (mainly signal level) from my C program?
I know that programs like airodump uses osdep routines but I dont know how to use it. Any help or orientation will be gratefull!!

thanks

Thank you szczepanczyk, but I would like to access to the information directly, without using an external program, it has to be possible I guess.. the iwconifg signal strength's information is not very precise

Hm. You can get the Kismet source code and check iwcontrol.cc file. There are ioctl functions which getting information that you need.

yes, that is one of the things I have in my TODO list : )

I have also found this interesting page with an api for wireless cards under linux, I will try to use it

Time to read and read code..

thanks for your advices
