SSL_get0_connection, SSL_is_connection - get a QUIC connection SSL object from a QUIC stream SSL object

#include <openssl/ssl.h>
SSL *SSL_get0_connection(SSL *ssl);
int SSL_is_connection(SSL *ssl);

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.

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.

These functions were added in OpenSSL 3.2.
