variable config parameters to driver.

Hi,

I want to pass config parameters to driver during loading time.
Important : Number of parameters are variable.
Currently on Linux, what we do is, we pass them via a config file.
Driver reads the config file during loading.
This config file is written by an Application.
Typical sequence of passing parameters to driver is:
Driver is loaded with default param.
Now Application starts, writes the config file.
Driver is unloaded and loaded.
Driver read the config file during loading and works accordingly.
One way to do on MAC OS is: Write them in Info.plist.
But what is the max size via Info.plist? On linux max size is 4K via config file.

Can I use the same mechanism for MAC OS? that is have a seperate config
file, not the Info.plist.
Because I want to reuse
(1) my appliation code, that writes the config file.
(2) driver's parser that reads the config file.

How can I read/write files in IOKit driver? Is it the right way do?
What are the other ways to pass these variable config parameters to driver? _______________________________________________
