Equivalent of 'Registry' structure of Windows in Linux
 

Hi
Is there any equivalent of the registry structure of Windows in Linux. I am working on device drivers and while working on Windows I used the 'registry' to store certain information that was stored by one driver and used by another driver at a later point in time.
How do i achieve this in Linux? Is creating a file the only way or is there any structure similiar to 'registry' which can be used?

There's no central registry, programs have their own cfg files as needed (in general).
However, for device drivers loaded into the kernel, see /etc/sysctl.conf.
Also
man sysctl

Hey Chris,
Thanks a lot for the reply.
I checked out the sysctl.conf file and the sysctl command. But i still dont understand how do i add a parameter. I assume(correct me if i am wrong) all the parameters are stored in the /proc/sys/ directory and only those entries can be manipulated using the sysctl command or the sysctl.conf file. But what if i want to create a new parameter and play around with it?

I dont know if this book will help: Linux Device Drivers:

You can add options in the /etc/modprobe.conf file.

Using the `modinfo' program, you can discover which options a kernel device driver accepts.
Other than that, the source code or header file or kernel Documentation may give information as well.
