=head1 NAME

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

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 SSL *SSL_get0_connection(SSL *ssl);
 int SSL_is_connection(SSL *ssl);

=head1 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.

=head1 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.
