clientSubscribeMutexInit()

int clientSubscribeMutexInit

(

)

Initialize the client subsribe mutex.

Definition at line 417 of file gena_ctrlpt.cpp.

Here is the caller graph for this function:

clientSubscribeMutexDestroy()

int clientSubscribeMutexDestroy

(

)

Destroy the client subsribe mutex.

Definition at line 429 of file gena_ctrlpt.cpp.

Here is the caller graph for this function:

genaUnregisterClient()

int genaUnregisterClient

(

UpnpClient_Handle

client_handle

)

Unsubcribes all the outstanding subscriptions and cleans the subscription list.

This function is called when control point unregisters.

Returns

UPNP_E_SUCCESS if successful, otherwise returns the appropriate error code.

Parameters

[in]

client_handle

Handle containing all the control point related information.

Definition at line 433 of file gena_ctrlpt.cpp.

Here is the call graph for this function:

genaUnSubscribe()

int genaUnSubscribe	(	UpnpClient_Handle	client_handle,
		const UpnpString *	in_sid
	)

Unsubscribes a SID.

It first validates the SID and client_handle,copies the subscription, sends UNSUBSCRIBE http request to service processes request and finally removes the subscription.

Returns

UPNP_E_SUCCESS if service response is OK, otherwise returns the appropriate error code.

Parameters

[in]	client_handle	UPnP client handle.
[in]	in_sid	The subscription ID.

genaSubscribe()

int genaSubscribe	(	UpnpClient_Handle	client_handle,
		const UpnpString *	PublisherURL,
		int *	TimeOut,
		UpnpString *	out_sid
	)

This function subscribes to a PublisherURL (also mentioned as EventURL in some places).

It sends SUBSCRIBE http request to service processes request. Finally adds a Subscription to the clients subscription list, if service responds with OK.

Returns

UPNP_E_SUCCESS if service response is OK, otherwise returns the appropriate error code

Parameters

[in]	client_handle	The client handle.
[in]	PublisherURL	Of the form: "http://134.134.156.80:4000/RedBulb/Event"
[in,out]	TimeOut	requested Duration: if -1, then "infinite". in the OUT case: actual Duration granted by Service, -1 for infinite.
[out]	out_sid	sid of subscription, memory passed in by caller.

Here is the caller graph for this function:

genaRenewSubscription()

int genaRenewSubscription	(	UpnpClient_Handle	client_handle,
		const UpnpString *	in_sid,
		int *	TimeOut
	)

Renews a SID.

It first validates the SID and client_handle and copies the subscription. It sends RENEW (modified SUBSCRIBE) http request to service and processes the response.

Returns

UPNP_E_SUCCESS if service response is OK, otherwise the appropriate error code.

Parameters

[in]	client_handle	Client handle.
[in]	in_sid	Subscription ID.
[in,out]	TimeOut	requested Duration, if -1, then "infinite". In the OUT case: actual Duration granted by Service, -1 for infinite.

gena_process_notification_event()

void gena_process_notification_event	(	SOCKINFO *	info,
		http_message_t *	event
	)

This function processes NOTIFY events that are sent by devices.

Parameters: IN SOCKINFO *info: Socket structure containing the device socket information IN http_message_t *event: The http message contains the GENA notification

Note

called by genacallback()

Parameters

[in]	info	Socket info of the device.
[in]	event	The http message contains the GENA notification.
