BOOL add_ssdp_message_to_cache	(	ssdp_cache_s **	ssdp_cache_pointer,
		ssdp_message_s **	ssdp_message_pointer
	)

Adds a ssdp message to a ssdp messages list. If the list hasn't been initialized then it is initialized first.

Parameters

ssdp_cache_pointer	The address of a pointer to a ssdp cache list.
ssdp_message_pointer	The ssdp message to be appended to the cache list.

Returns

TRUE on success, exits on failure.

Definition at line 290 of file ssdp_cache.c.

static BOOL create_plain_text_message ( char *  results, int  buffer_size, ssdp_message_s *  ssdp_message  )

static

Create a plain-text message.

Parameters

results	The buffer to store the results in.
buffer_size	The size of the buffer 'results'.
message	The message to convert.

Definition at line 30 of file ssdp_cache.c.

BOOL flush_ssdp_cache	(	configuration_s *	conf,
		ssdp_cache_s **	ssdp_cache_pointer,
		const char *	url,
		struct sockaddr_storage *	sockaddr_recipient,
		int	port,
		int	timeout
	)

Send and free the passed SSDP cache.

Parameters

conf	The configuration to use.
ssdp_cache_pointer	The SSDP cache to send and delete (flush).
url	The URL (without the protocol and IP) to send the data to.
sockaddr_recipient	The socket address to send to.
port	The port to send to.
timeout	The send-timeout to set.

Returns

TRUE on success, FALSE otherwise.

static void free_ssdp_cache ( ssdp_cache_s **  ssdp_cache_pointer )

static

Frees all the elements in the ssdp messages list.

Parameters

ssdp_cache_pointer

The ssdp cache list to be cleared.

Definition at line 241 of file ssdp_cache.c.

static int send_stuff ( const char *  url, const char *  data, const struct sockaddr_storage *  da, int  port, int  timeout, configuration_s *  conf  )

static

Send the SSDP cache to the given address (aka. forwarder).

Parameters

url	The URL (without the protocol and IP) to send the data to.
data	The data to send.
da	The socket address to send to.
