OSSL_PARAM_PRINT_TO_BIO(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

🌸 NAME 🌸

OSSL_PARAM_print_to_bio — the OSSL_PARAM interrogation utilities, bestie. This is the 3ossl manual page, and yes, it's giving “tiny but useful” energy ✨

🎀 SYNOPSIS 🎀

okay so here’s the include and the function signature, copy-paste girlies:

#include <openssl/params.h>

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

💅 DESCRIPTION 💅

OSSL_PARAM_print_to_bio() formats each parameter contained in the passed-in array of OSSL_PARAM values p, and prints both the key — and optionally its value — to a provided BIO. Iconic little printing behavior, no cap.

p must be a non-null array of OSSL_PARAM values, terminated with a value containing a null key member. Yes, that terminator matters, bestie — it’s the “we’re done here” marker 🫶

print_values is a control parameter, indicating that key values should be printed, in addition to key names. So if you want the receipts — keys and values — that’s what this switch is for 💖

⭐ RETURN VALUES ⭐

OSSL_PARAM_print_to_bio() returns 1 on success, and 0 on failure. Simple, clean, slay 💅
