int SSL_get_read_ahead(const SSL *s);

=head1 DESCRIPTION
|
||
|
|
|
||
|
|
SSL_CTX_set_read_ahead() and SSL_set_read_ahead() set whether we should read as
|
||
|
|
many input bytes as possible (for non-blocking reads) or not. 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.
