OPENSSL_APPLINK(3ossl)

💖 OPENSSL_APPLINK 💖

okay bestie, welcome to OPENSSL_Applink from the OpenSSL fam — this is the page for the little glue module that keeps OpenSSL's BIO layer and the Win32 compiler run-time on speaking terms 🫶. it's giving backstage pass, not front-of-house, and we're gonna talk about why.

---

✨ NAME ✨

OPENSSL_Applink — the glue between OpenSSL BIO and the Win32 compiler run-time, no cap.

---

✨ SYNOPSIS ✨

__declspec(dllexport) void **OPENSSL_Applink();

---

✨ DESCRIPTION ✨

so OPENSSL_Applink is an application-side interface that provides a glue between the OpenSSL BIO layer and the Win32 compiler run-time environment. yes, it lives on the application side, but plot twist — it's essentially an OpenSSL private interface. 🫣

because of that, application developers are not expected to implement it themselves. instead, the move is:

1. compile the provided module with a compiler of your choice 🎀
2. link it into the target application 💅

the module in question ships as applink.c, and it's located alongside the public header files — but only on the platforms where it's applicable, iykyk. 🌸

lowkey the whole vibe here is "don't write this yourself, just build the file we gave you and link it in." that's it, that's the task. 🧚

✨ RETURN VALUES ✨

Not available. 😭 (yeah, there's literally nothing to report back here, don't come for me)
