OPENSSL_APPLINK(3SSL)

💖 NAME 💖

OPENSSL_Applink — the lil glue situation between OpenSSL BIO and the Win32 compiler run-time, bestie 🫶

---

✨ SYNOPSIS ✨

__declspec(dllexport) void **OPENSSL_Applink();

---

🎀 DESCRIPTION 🎀

okay so OPENSSL_Applink is an application-side interface that literally exists to be the glue between the OpenSSL BIO layer and the Win32 compiler run-time environment. it's giving matchmaker, it's giving bridge ✨

but here's the tea: even though it looks like it lives on the application side, it's essentially OpenSSL private interface. so no, bestie, application developers are not expected to implement it themselves 🙈. what you're supposed to do instead is compile the provided module with the compiler of your choice and link it into the target application. that's the whole vibe. 👑

the module in question ships as applink.c, and it lives right alongside the public header files — but only on the platforms where it's applicable, so don't come looking for it everywhere, iykyk 🦋
