OSSL_PARAM_PRINT_TO_BIO(3ossl)

✨ OSSL_PARAM_PRINT_TO_BIO ✨

okay bestie, gather round, because we're about to talk about OSSL_PARAM_print_to_bio from the 3ossl manual — aka your little interrogation buddy for OSSL_PARAM stuff 💅 no cap, it's giving "let me peek at what's in this param array" energy and honestly? iconic.

🌸 SYNOPSIS 🌸

#include <openssl/params.h>

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

🦋 DESCRIPTION 🦋

so here's the tea, bestie 🍓 — OSSL_PARAM_print_to_bio() takes that array of OSSL_PARAM values you passed in as p, formats every single parameter inside it, and prints them out to the BIO you hand it. ✨

and the way it prints the key... and then optionally the value too? obsessed. literally the main character move.

now, p has rules, and we respect them 👑 — it must be a non-null array of OSSL_PARAM values, and it has to be terminated with a value that contains a null key member. that's the little "we're done here" signal, iykyk. no terminator, no vibe.

then there's print_values, which is your control parameter 💜 — it's the lil switch that says "yes queen, print the key values too, in addition to just the key names." so:

• print_values set → key names and values get printed 💖
• print_values not set → just the key names, keep it mysterious 🙈

---

⭐ RETURN VALUES ⭐

OSSL_PARAM_print_to_bio() is a simple girl in that way:

• returns 1 on success 🎀
• returns 0 on failure 💀

that's it. that's the whole range. no in-between, no situationship.

🔥 HISTORY 🔥

OSSL_PARAM_print_to_bio() was added in OpenSSL 3.5 — so it's a newer addition, freshly on the scene, and we love that for it 🌈
