SSL_GET0_CONNECTION(3ossl)

✨ SSL_get0_connection ✨

ok so bestie, this is the 3ossl manual page for SSL_get0_connection and SSL_is_connection, and it's literally all about finding your way back home when you're a QUIC stream SSL object. it's giving "who's your mom" but for TLS objects 💖

---

🌸 NAME 🌸

SSL_get0_connection, SSL_is_connection — get a QUIC connection SSL object from a QUIC stream SSL object 🦋

---

🎀 SYNOPSIS 🎀

#include <openssl/ssl.h>

SSL *SSL_get0_connection(SSL *ssl);
int SSL_is_connection(SSL *ssl);

like. two functions. two lines. no cap. 💅

---

💜 DESCRIPTION 💜

ok so SSL_get0_connection() is the friend that helps you find your group chat. when you call it on a QUIC stream SSL object, it returns the QUIC connection SSL object that this stream belongs to. found family fr fr 🫶

when you call it on a QUIC connection SSL object, it just returns the same object. like yeah babe, you're already home ✨

and when you call it on a non-QUIC object? it returns the same object you passed in. no notes, no drama, just identity 💅

then there's SSL_is_connection() which is the vibe check function:

• returns 1 for QUIC connection SSL objects ✅
• returns 1 for non-QUIC SSL objects ✅
• returns 0 for QUIC stream SSL objects ❌

so basically it's asking "are you a connection or are you a stream?" and streams are the only ones getting a no 😭

---

🔥 RETURN VALUES 🔥

SSL_get0_connection() returns the QUIC connection SSL object — but only when you give it a QUIC stream SSL object. otherwise it hands back the same SSL object you passed it. and the iconic part: it always returns non-NULL. never leaves you on read. periodt 👑

SSL_is_connection() returns 1 if the SSL object is not a QUIC stream SSL object, and 0 otherwise. that's it. that's the whole personality 💀
