+\& #include <openssl/ssl.h>
+\&
+\& #define SSL_ACCEPT_STREAM_NO_BLOCK

+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+The \fBSSL_accept_stream()\fR function attempts to dequeue an incoming stream from the
+given QUIC connection SSL object and returns the newly allocated QUIC stream SSL
+object.
+.PP
+If the queue of incoming streams is empty, this function returns NULL (in
+nonblocking mode) or waits for an incoming stream (in blocking mode). This
+function may still return NULL in blocking mode, for example if the underlying
+connection is terminated.
+.PP
+The caller is responsible for managing the lifetime of the returned QUIC stream
+SSL object; for more information, see \fBSSL_free\fR\|(3).
+.PP
+This function will block if the QUIC connection SSL object is configured in
+blocking mode (see \fBSSL_set_blocking_mode\fR\|(3)), but this may be bypassed by
+passing the flag \fBSSL_ACCEPT_STREAM_NO_BLOCK\fR in \fIflags\fR. If this flag is set,
+this function never blocks.
+.PP
+Calling \fBSSL_accept_stream()\fR if there is no default stream already present
+inhibits the future creation of a default stream. See \fBopenssl\-quic\fR\|(7).
+.PP
+\&\fBSSL_get_accept_stream_queue_len()\fR returns the number of incoming streams
+currently waiting in the accept queue.
+.PP
+These functions can be used from multiple threads for the same QUIC connection.
+.PP
+Depending on whether default stream functionality is being used, it may be
+necessary to explicitly configure the incoming stream policy before streams can
+be accepted; see \fBSSL_set_incoming_stream_policy\fR\|(3). See also
+"MODES OF OPERATION" in \fBopenssl\-quic\fR\|(7) for more information on default stream
+functionality.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBSSL_accept_stream()\fR returns a newly allocated QUIC stream SSL object, or NULL if
+no new incoming streams are available, or if the connection has been terminated,
+or if called on a SSL object other than a QUIC connection SSL object.
+\&\fBSSL_get_error\fR\|(3) can be used to obtain further information in this case.
+.PP
+\&\fBSSL_get_accept_stream_queue_len()\fR returns the number of incoming streams
+currently waiting in the accept queue, or 0 if called on a SSL object other than
+a QUIC connection SSL object.
