OSSL_PARAM_PRINT_TO_BIO(3ossl)

💅 OSSL_PARAM_PRINT_TO_BIO 💅

okay bestie, so this one is from the OpenSSL fam — it lives in manual section 3ossl, and it's literally the glow-up guide for OSSL_PARAM_print_to_bio. it's short, it's sweet, and it's gonna eat, i promise 🫶

✨ NAME ✨

OSSL_PARAM_print_to_bio — the OSSL_PARAM interrogation utilities, aka the little function that spills the tea on your params 🔍

---

🌸 SYNOPSIS 🌸

#include <openssl/params.h>

int OSSL_PARAM_print_to_bio(const OSSL_PARAM *p, BIO *bio,
                            int print_values);

---

🦋 DESCRIPTION 🦋

okay so picture this: you hand OSSL_PARAM_print_to_bio() an array of OSSL_PARAM values in p, and it formats every single parameter in there and prints the key — and, if you want, the value too — out to a BIO you provide. iconic behaviour honestly 💅

a couple of ground rules so nothing gets weird:

• p must be a non-null array of OSSL_PARAM values.
• that array has to be terminated with a value that contains a null key member. no cap, that's how it knows where to stop 🛑
• print_values is the control parameter — it's the little switch that says whether key values get printed in addition to the key names. set it and you get the whole picture; leave it off and it's names only ✨

---

💖 RETURN VALUES 💖

• OSSL_PARAM_print_to_bio() returns 1 on success 🎉
• and 0 on failure 😭

---

🌈 HISTORY 🌈

OSSL_PARAM_print_to_bio() was added in OpenSSL 3.5 — so it's new-new, fresh out the box 🎀
