Data Structures
struct	SearchResultJob
struct	ctrlpt_cb

Macros
#define	_poll(fds, nfds, timeout)

Typedefs
typedef struct ctrlpt_cb	CtrlptCallback

Functions
static void	ctrlpt_callback_enter (CtrlptCallback *self, int handle, int searchId)
	Marks a discovery callback as running. Called with the handle lock held, so whoever ends the search or unregisters the client afterwards waits for the callback.
static void	ctrlpt_callback_leave (CtrlptCallback *self)
	Marks a discovery callback as finished.
static void	free_search_result (void *arg)
static void	send_search_result (void *arg)
	Sends a callback to the control point application with a SEARCH result, unless the search ended or the client unregistered after the result was queued.
static int	CreateClientRequestPacket (char *RqstBuf, size_t RqstBufSize, int Mx, char *SearchTarget, int AddressFamily)
	Creates a HTTP search request packet depending on the input parameter.
static void	searchExpired (void *arg)
SSDP Control Point Functions
void	ssdp_wait_ctrlpt_callbacks (int handle, int searchId)
	Waits until no discovery callback of the given client is running: search results of the given search, or with searchId -1 every search result and advertisement. Returns at once when called from such a callback. The caller must not hold the handle lock.
void	ssdp_handle_ctrlpt_msg (http_message_t *hmsg, struct sockaddr_storage *dest_addr, int timeout)
	This function handles the ssdp messages from the devices. These messages includes the search replies, advertisement of device coming alive and bye byes.
int	SearchByTarget (int Hnd, int Mx, char *St, void *Cookie)
	Creates and send the search request for a specific URL.
