OSSL_QUIC_CLIENT_METHOD(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💖 NAME 💖

Okay so bestie, welcome to the 3ossl manual page for OSSL_QUIC_CLIENT_METHOD — aka the QUIC method squad 💅. These functions provide SSL_METHOD objects for QUIC enabled functions:

  • OSSL_QUIC_client_method — the no-threads client method.
  • OSSL_QUIC_client_thread_method — the threaded client method.
  • OSSL_QUIC_server_method — the server-side method.

✨ SYNOPSIS ✨

#include <openssl/quic.h>

const SSL_METHOD *OSSL_QUIC_client_method(void);
const SSL_METHOD *OSSL_QUIC_client_thread_method(void);
const SSL_METHOD *OSSL_QUIC_server_method(void);

🦋 DESCRIPTION 🦋

Okay so the trio — OSSL_QUIC_client_method(), OSSL_QUIC_client_thread_method(), and OSSL_QUIC_server_method() — are literally the methods you feed to SSL_CTX_new_ex(3) when you want QUIC protocol support. Slay.

  • OSSL_QUIC_client_thread_method() — uses threads to allow for a blocking mode of operation and avoid the need to return control to the OpenSSL library for processing time based events. It's giving “threads handle the waiting, bestie” energy 🧵✨.
  • OSSL_QUIC_client_method() — does not use threads and depends on nonblocking mode of operation and the application periodically calling SSL functions. So yeah, you gotta check in on it like a group chat 💬.
  • OSSL_QUIC_server_method() — provides server-side QUIC protocol support and must be used with the SSL_new_listener(3) API. Attempting to use OSSL_QUIC_server_method() with SSL_new(3) will result in an error. No cap, that combo is a no 🙈.

🌈 RETURN VALUES 🌈

These functions return pointers to the constant method objects. Periodt. That's the whole return vibe — constant method object pointers, iconic 👑.
