SSL_get0_connection(3)              OpenSSL             SSL_get0_connection(3)


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
       The SSL_get0_connection() function, when called on a QUIC stream SSL
       object, returns the QUIC connection SSL object which the QUIC stream
       SSL object belongs to.

       When called on a QUIC connection SSL object, it returns the same
       object.

       When called on a non-QUIC object, it returns the same object it was
       passed.

       SSL_is_connection() returns 1 for QUIC connection SSL objects and for
       non-QUIC SSL objects, but returns 0 for QUIC stream SSL objects.

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.

       SSL_is_connection() returns 1 if the SSL object is not a QUIC stream
       SSL object and 0 otherwise.
