Equivalent of 'Registry' structure of Windows in Linux
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?
