+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fISSL_CTX_set_read_ahead()\fR and \fISSL_set_read_ahead()\fR set whether we should read as
+many input bytes as possible (for non-blocking reads) or not. For example if
+\&\fBx\fR bytes are currently required by OpenSSL, but \fBy\fR bytes are available from
+the underlying \s-1BIO \s0(where \fBy\fR > \fBx\fR), then OpenSSL will read all \fBy\fR bytes
+into its buffer (providing that the buffer is large enough) if reading ahead is
+on, or \fBx\fR bytes otherwise. The parameter \fByes\fR or \fBm\fR should be 0 to ensure
+reading ahead is off, or non zero otherwise.
+.PP
+SSL_CTX_set_default_read_ahead is a synonym for SSL_CTX_set_read_ahead, and
+SSL_CTX_get_default_read_ahead is a synonym for SSL_CTX_get_read_ahead.
+.PP
+\&\fISSL_CTX_get_read_ahead()\fR and \fISSL_get_read_ahead()\fR indicate whether reading
+ahead has been set or not.
+.SH "NOTES"
+.IX Header "NOTES"
+These functions have no impact when used with \s-1DTLS.\s0 The return values for
+\&\fISSL_CTX_get_read_head()\fR and \fISSL_get_read_ahead()\fR are undefined for \s-1DTLS.\s0
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+SSL_get_read_ahead and SSL_CTX_get_read_ahead return 0 if reading ahead is off,
