OSSL_QUIC_client_method(3)          OpenSSL         OSSL_QUIC_client_method(3)


NAME
       OSSL_QUIC_client_method, OSSL_QUIC_client_thread_method,
       OSSL_QUIC_server_method - Provide SSL_METHOD objects for QUIC enabled
       functions

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
       The OSSL_QUIC_client_method(), OSSL_QUIC_client_thread_method(), and
       OSSL_QUIC_server_method() functions provide methods for the
       SSL_CTX_new_ex(3) function to provide QUIC protocol support.

       The 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.  The
       OSSL_QUIC_client_method() does not use threads and depends on
       nonblocking mode of operation and the application periodically calling
       SSL functions.

       The 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.

RETURN VALUES
       These functions return pointers to the constant method objects.

SEE ALSO

HISTORY
       OSSL_QUIC_client_method() and OSSL_QUIC_client_thread_method() were
       added in OpenSSL 3.2.

       OSSL_QUIC_server_method() was added in OpenSSL 3.5.
