## 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.

## X_USER_AGENT

can be overwritten by configure CFLAGS argument. The {\tt X_USER_AGENT} constant specifies the value of the X-User-Agent: HTTP header. The value "redsonic" is needed for the DSM-320. See https://sourceforge.net/forum/message.php?msg_id=3166856 for more information
