.SH DESCRIPTION
.IX Header "DESCRIPTION"
The \fBSSL_get0_connection()\fR function, when called on a QUIC stream SSL object,
returns the QUIC connection SSL object which the QUIC stream SSL object belongs
to.
.PP
When called on a QUIC connection SSL object, it returns the same object.
.PP
When called on a non-QUIC object, it returns the same object it was passed.
.PP
\&\fBSSL_is_connection()\fR returns 1 for QUIC connection SSL objects and for non-QUIC
SSL objects, but returns 0 for QUIC stream SSL objects.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBSSL_get0_connection()\fR 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.
.PP
\&\fBSSL_is_connection()\fR returns 1 if the SSL object is not a QUIC stream SSL object
and 0 otherwise.
