OSSL_CORE_MAKE_FUNC(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 OSSL_CORE_MAKE_FUNC — OpenSSL's reserved symbols, bestie

okay so this is the 3ossl manual page, and ngl it's a short one — but it's important, so pay attention 🫶

✨ NAME ✨

OSSL_CORE_MAKE_FUNC, SSL_OP_BIT, EXT_UTF8STRING — these are the OpenSSL reserved symbols. Like, VIP-only. Backstage pass only. Not for you (no offense, ily 💖).

🌸 SYNOPSIS 🌸

#include <openssl/core_dispatch.h>

#define OSSL_CORE_MAKE_FUNC(type,name,args)
#define SSL_OP_BIT(n)
#define EXT_UTF8STRING(nid)

look at those three little macros. they look innocent. they are not for application use, bestie 😭

🦋 DESCRIPTION 🦋

so here's the tea ☕ — there are certain macros that may show up in OpenSSL header files, and they are reserved for internal use. Like, OpenSSL-internal. House business. 👑

Two things you need to know, and they're both basically the same thing:

  • Don't use them in your applications.
  • Don't assume they exist — like, don't build your whole personality around a macro that might just... not be there next version 🙈

And to be super clear: all the macros listed in the synopsis above are reserved. Every single one. OSSL_CORE_MAKE_FUNC, SSL_OP_BIT, EXT_UTF8STRING — the whole squad is off-limits 💀

fr fr, if you're reaching for these, ask yourself why. OpenSSL is telling you no. Respect the no. 🚫

⭐ RETURN VALUES ⭐

Not applicable. 💁‍♀️

(They're macros, bestie. There's nothing to return. The vibe check is: not applicable.)

🌈 HISTORY 🌈

The macros described here were added in OpenSSL 3.0. so they're not ancient relics, they're modern-era reserved symbols 🎀
