sockets related functionalities on Fedora Linux

[Abid Ghufran]

Dear All,

I am working on a networking application using socket and C programming. I 
need a functionality to manipulate routing table and for that I need SYSCTL 
API (it is part of socket interface). Now, the problem is that I cannot find 
the relevant library. I have to do this work using IOCTL API but it is not 
as versatile as the SYSCTL. Further, when I ran a script that checks the 
funcionalities (libraries) present on the system, it said that Fedora Core 
-4/5 which I am using, do not have the lirbaries. Same thing happened when I 
was looking for API to access the Data Link Layer and packet 
generation/sniffing operations.

The impression I am getting is that Unix supports a much wider range of 
sockets related functionalities than Linux, as the material (Stevens, 
Sockets Programming book) I am following refers to Unix for all such 
functionalities in explanations.

Is there any way I could add these libraries? For this do I have to 
recompile the kernel?

Thank you very much,

Abid Ghufran.
