You may have a look at:

https://docs.rtems.org/branches/master/c-user/initialization.html

https://docs.rtems.org/branches/master/c-user/config/index.html

I think your question is not really well answered by our current 
documentation set. While you read the documentation please always try to 
improve it. I you think something is missing or could be better 
explained, then just send patches.

Independent of the documentation you should set up a test environment 
with GDB support. You can set a break point to Init(). This points you 
to the code which determines the argument value.
