SSL_SESSION_GET_COMPRESS_ID(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

✨ SSL_SESSION_GET_COMPRESS_ID 💅

okay bestie, so this one is from the OpenSSL manual, section 3ossl — it's called SSL_SESSION_GET_COMPRESS_ID(3ossl) and honestly? it's a lil cutie. tiny page, one job, does it slay. let's get into it 🎀

🌸 NAME 🌸

SSL_SESSION_get_compress_id — get the deets about the compression that's associated with a session 🫶

✨ SYNOPSIS ✨

like, first you gotta include the header, periodt:

#include <openssl/ssl.h>

unsigned int SSL_SESSION_get_compress_id(const SSL_SESSION *s);

that's it. that's the whole vibe check. 💖

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓 — if compression has actually been negotiated for an ssl session, then SSL_SESSION_get_compress_id() will hand you back the id for the compression method. and if it hasn't? it just returns 0. no drama, no notes. 💀

and ngl, the compression method menu is short — like, tragically short. the only built-in supported compression method is zlib, and its id is 1. that's the entire lineup. one (1) whole option. iconic in a minimal way honestly 👑

🎀 RETURN VALUES 🎀

SSL_SESSION_get_compress_id() returns the id of the compression method — or 0 if there isn't one. that's it, that's the return value. 🧚
