Functions

• int tls_ct_wq_add (tls_ct_q **ct_q, const void *data, unsigned int size)

  Wrapper over tls_ct_q_add().
  

• void tls_ct_wq_destroy ()

  Destroy clear text write queues support.
  

• int tls_ct_wq_flush (struct tcp_connection *c, tls_ct_q **tc_q, int *flags, int *ssl_err)

  Wrapper over tls_ct_q_flush().
  

• unsigned int tls_ct_wq_free (tls_ct_q **ct_q)

  Wrapper over tls_ct_q_destroy() Wrapper over tls_ct_q_destroy(), besides doing a tls_ct_q_destroy it also keeps track of the total queued bytes.
  

• int tls_ct_wq_init ()

  Init clear text write queues support.
  

• unsigned int tls_ct_wq_total_bytes ()

  Total number of written queued bytes in all the SSL connections.

Function Documentation

int tls_ct_wq_add	(	tls_ct_q **	ct_q,
		const void *	data,
		unsigned int	size
	)

Wrapper over tls_ct_q_add(), besides doing a tls_ct_q_add it also keeps track of queue size and total queued bytes. If the maximum queue size is exceeded => error.

Parameters:

	ct_q	clear text queue
	data	data
	size	data size

Returns:

0 on success, < 0 on error (-1 memory allocation, -2 queue size too big).

int tls_ct_wq_flush	(	struct tcp_connection *	c,
		tls_ct_q **	ct_q,
		int *	flags,
		int *	ssl_err
	)

Wrapper over tls_ct_q_flush(), besides doing a tls_ct_q_add it also keeps track of queue size and total queued bytes.

Parameters:

	c	TCP connection
	ct_q	clear text queue
	flags	filled,

See also:

tls_ct_q_add() for more details.

Parameters:

ssl_err

set to the SSL err (SSL_ERROR_NONE on full success).

Returns:

-1 on internal error, or the number of bytes flushed on success (>=0).
