Functions
SSDP Server Functions
int	AdvertiseAndReply (int AdFlag, UpnpDevice_Handle Hnd, enum SsdpSearchType SearchType, struct sockaddr DestAddr, char DeviceType, char DeviceUDN, char ServiceType, int Exp)
	Sends SSDP advertisements, replies and shutdown messages.
int	unique_service_name (char cmd, SsdpEvent Evt)
	Fills the fields of the event structure like DeviceType, Device UDN and Service Type.
enum SsdpSearchType	ssdp_request_type1 (char *cmd)
	This function figures out the type of the SSDP search in the in the request.
int	ssdp_request_type (char cmd, SsdpEvent Evt)
	Starts filling the SSDP event structure based upon the request received.
int	readFromSSDPSocket (SOCKET socket)
	This function reads the data from the ssdp socket.
int	get_ssdp_sockets (MiniServerSockArray *out)
	Creates the IPv4 and IPv6 ssdp sockets required by the control point and device operation.
SSDP Control Point Functions
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.
SSDP Device Functions
void	advertiseAndReplyThread (void *data)
	Wrapper function to reply the search request coming from the control point.
void	ssdp_handle_device_request (http_message_t hmsg, struct sockaddr_storage dest_addr)
	Handles the search request. It does the sanity checks of the request and then schedules a thread to send a random time reply (random within maximum time given by the control point to reply).
int	DeviceAdvertisement (char DevType, int RootDev, char Udn, char *Location, int Duration, int AddressFamily, int PowerState, int SleepPeriod, int RegistrationState)
	Creates the device advertisement request based on the input parameter, and send it to the multicast channel.
int	SendReply (struct sockaddr DestAddr, char DevType, int RootDev, char Udn, char Location, int Duration, int ByType, int PowerState, int SleepPeriod, int RegistrationState)
	Creates the reply packet based on the input parameter, and send it to the client addesss given in its input parameter DestAddr.
int	DeviceReply (struct sockaddr DestAddr, char DevType, int RootDev, char Udn, char Location, int Duration, int PowerState, int SleepPeriod, int RegistrationState)
	Creates the reply packet based on the input parameter, and send it to the client address given in its input parameter DestAddr.
int	ServiceAdvertisement (char Udn, char ServType, char *Location, int Duration, int AddressFamily, int PowerState, int SleepPeriod, int RegistrationState)
	Creates the advertisement packet based on the input parameter, and send it to the multicast channel.
int	ServiceReply (struct sockaddr DestAddr, char ServType, char Udn, char Location, int Duration, int PowerState, int SleepPeriod, int RegistrationState)
	Creates the advertisement packet based on the input parameter, and send it to the multicast channel.
int	ServiceShutdown (char Udn, char ServType, char *Location, int Duration, int AddressFamily, int PowerState, int SleepPeriod, int RegistrationState)
	Creates a HTTP service shutdown request packet and sends it to the multicast channel through RequestHandler.
int	DeviceShutdown (char DevType, int RootDev, char Udn, char *Location, int Duration, int AddressFamily, int PowerState, int SleepPeriod, int RegistrationState)
	Creates a HTTP device shutdown request packet and send it to the multicast channel through RequestHandler.
