It's guaranteed by ABI.

Yes from main, because you got a pointer to argv and nothing can have modified
them yet.

After main(), even if you get a pointer to them, you can't be sure they
haven't been modified / clobbered / overwritten, so that's not useful.

On Windows, GetCommandLineW() is always valid.
