That's literally it — it's the little bundle of settings that says "hey, here's how you should set yourself up" before anything else happens. Lowkey the first thing you gotta deal with. Periodt.

🎀 Field Documentation 🎀

⭐ char struct_id[4]

The eyecatcher for this structure. It Must be MQTG. No cap, it has to be exactly that — it's how the struct checks its own vibe 💀

⭐ int struct_version

The version number of this structure. It Must be 0. That's the whole rule. Don't get creative with it, bestie 🙈

⭐ int do_openssl_init

Who's doing the openssl init, you or the library? Pick your fighter:

• 1 = we do openssl init 👑 (the library handles it)
• 0 = leave it to the application 🫶 (you're on your own, main character)
