While I'm waiting for a response from mobile-sig, I'm going through the documentation (and something called "fossies") of importlib. I hope that it's okay to ask some follow up questions...even though I've redirected this post to mobile-sig.
If it is, my first question(s) is/are about the import machinery and C-extension modules. Assuming that C-extension modules are ones that include files that are named as *.c, how does the import machinery handle specified shared libraries, such as -ldl? Additionally, how does the import machinery handle the symbols from those libraries...if it does at all?
