For example if +B<x> bytes are currently required by OpenSSL, but B<y> bytes are available from +the underlying BIO (where B<y> > B<x>), then OpenSSL will read all B<y> bytes +into its buffer (providing that the buffer is large enough) if reading ahead is +on, or B<x> bytes otherwise. The parameter B<yes> or B<m> should be 0 to ensure +reading ahead is off, or non zero otherwise. + +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. + +SSL_CTX_get_read_ahead() and SSL_get_read_ahead() indicate whether reading +ahead has been set or not. + +=head1 NOTES + +These functions have no impact when used with DTLS. The return values for +SSL_CTX_get_read_head() and SSL_get_read_ahead() are undefined for DTLS. + +=head1 RETURN VALUES + +SSL_get_read_ahead and SSL_CTX_get_read_ahead return 0 if reading ahead is off, +and non zero otherwise. + +=head1 SEE ALSO + +L<ssl(3)|ssl(3)> + +=cut |
