65 \&\- OpenSSL Guide: Writing a simple blocking QUIC client
71 QUIC is non-standard and will not be supported by real world servers. This is
76 (see \fBossl\-guide\-libraries\-introduction\fR\|(7), \fBossl\-guide\-tls\-introduction\fR\|(7)
77 and \fBossl\-guide\-quic\-introduction\fR\|(7)); and that you know how to
82 \&\fBossl\-guide\-tls\-client\-block\fR\|(7). Only the differences between that client and
87 tutorial will discuss how to write a multi-stream client (see
88 \&\fBossl\-guide\-quic\-multi\-stream\fR\|(7)).
