13 - OpenSSL Guide: Writing a simple blocking QUIC client
20 QUIC is non-standard and will not be supported by real world servers. This is
25 (see L<ossl-guide-libraries-introduction(7)>, L<ossl-guide-tls-introduction(7)>
26 and L<ossl-guide-quic-introduction(7)>); and that you know how to

36 tutorial will discuss how to write a multi-stream client (see
