SSL_GET0_CONNECTION(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

okay so bestie, welcome to the 3ossl manual page for the two little functions that help you find a QUIC connection from a stream: SSL_get0_connection and SSL_is_connection 💅✨

🎀 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);

🦋 DESCRIPTION 🦋

okay so picture this: you call SSL_get0_connection() on a QUIC stream SSL object, and it gives you back the QUIC connection SSL object that this stream belongs to. Like, the stream's home base, y'know? 🏠

Call it on a QUIC connection SSL object, and it just hands you back the same object. No drama, no detour. 🫶

Call it on a non-QUIC object, and it returns the same object it was passed. It's giving "you are already here" energy, honestly.

SSL_is_connection() is the vibe check: it returns 1 for QUIC connection SSL objects and for non-QUIC SSL objects, but returns 0 for QUIC stream SSL objects. So if it's a stream, it's a no 💀; otherwise yes.

👑 RETURN VALUES 👑

SSL_get0_connection() returns the QUIC connection SSL object (for a QUIC stream SSL object), and otherwise returns the same SSL object passed. It always returns non-NULL — like, never NULL, periodt. 🫶

SSL_is_connection() returns 1 if the SSL object is not a QUIC stream SSL object and 0 otherwise. Simple as that, bestie.

⭐ HISTORY ⭐

These functions were added in OpenSSL 3.2. iconic behavior, honestly.
