That's not a simple question and without a deep knowledge of the code nothing I said would mean a whole lot, but the answer is that there's a superimposed implementation of the SP's RequestMapper plugin interface that gets injected that chains the SP config back down into Apache config so that Apache settings override the XML supplied settings.

The default values should be documented in the wiki. Those two specifically are "default" and nothing, respectively. The "default" string is a hardwired name for the application defined by the ApplicationDefaults element in the SP configuration and can't be changed. It's just a fallback to guarantee there's always an ID with nobody having to set one.

If you're asking what the default value of those specific C variables is, they don't have one, they're null.
