💖 SSL_CTX_CTRL 💖

okay so bestie, this is the SSL_CTX_CTRL page from the 3SSL manual, and honestly? it's giving backstage pass. no cap.

✨ NAME ✨

SSL_CTX_ctrl, SSL_CTX_callback_ctrl, SSL_ctrl, SSL_callback_ctrl — the internal handling functions for SSL_CTX and SSL objects 🎀

---

✨ SYNOPSIS ✨

✨ DESCRIPTION ✨

so the SSL_*_ctrl() family is the little squad of functions that manipulates settings on SSL_CTX and SSL objects. 🌸

depending on which command gets passed in as cmd, the arguments larg, parg, or fp get evaluated. it's a whole vibe check per command, basically.

⚠️ but here's the thing — these functions should never be called directly. like, not even once. 🙈

all the functionality you actually need is made available via other functions or macros, so go through those. periodt. 💅

---

✨ RETURN VALUES ✨

the return values of the SSL*_ctrl() functions depend on the command supplied via the cmd parameter. so like, it's not one answer, it's whatever the command decided. iykyk. 🌈
