Public Member Functions
onion_response *	onion_response_new (onion_request *req)
	Generates a new response object.
onion_connection_status	onion_response_free (onion_response *res)
	Frees the memory consumed by this object.
void	onion_response_set_header (onion_response res, const char key, const char *value)
	Adds a header to the response object.
void	onion_response_set_length (onion_response *res, size_t len)
	Sets the header length. Normally it should be through set_header, but as its very common and needs some procesing here is a shortcut.
void	onion_response_set_code (onion_response *res, int code)
	Sets the return code.
static void	write_header (onion_response res, const char key, const char *value, int flags)
	Helper that is called on each header, and writes the header.
int	onion_response_write_headers (onion_response *res)
	Writes all the header to the given response.
ssize_t	onion_response_write (onion_response res, const char data, size_t length)
	Write some response data.
ssize_t	onion_response_printf (onion_response res, const char fmt,...)
	Writes some data to the response. Using sprintf format strings.
ssize_t	onion_response_vprintf (onion_response res, const char fmt, va_list args)
	Writes some data to the response. Using sprintf format strings. va_list args version.
const char *	onion_response_code_description (int code)
	Returns a const char * string with the code description.

Data Fields
onion_request *	request
onion_dict *	headers
	Original request, so both are related, and get connected to the onion_t structure. Writes through the request connection.
int	code
	Headers to write when appropiate.
int	flags
	Response code.
unsigned int	length
	Flags.
unsigned int	sent_bytes
	Length, if known, of the response, to create the Content-Lenght header.
unsigned int	sent_bytes_total
	Sent bytes at content.
char	buffer [ONION_RESPONSE_BUFFER_SIZE]
	Total sent bytes, including headers.
off_t	buffer_pos
	buffer of output data. This way its do not send small chunks all the time, but blocks, so better network use. Also helps to keep alive connections with less than block size bytes.
