Connection and Channel ServicePoint interfaces

Connection and Channel ServicePoint interfaces — client-side wrappers for the ServicePoint interfaces

Description

In some protocols, mainly those that interact with the PSTN, it's possible to contact the emergency services or other public service answering points. The ServicePoint interfaces on the Connection and Channel can be used to discover how to contact these service points, and detect whether a call in progress is communicating with a service point.

This section documents the auto-generated C wrappers for the ServicePoint interfaces, used with TpConnection and TpChannel objects.

                                                         GError **error);

Connect a handler to the signal ServicePointChanged.

<p>Emitted when a channel changes the service point that it's connected to. This might be a new call being connected to a service, a call connected to a service being routed to a different service (ie, an emergency call being routed from a generic emergency PSAP to a poison control PSAP), or any number of other things.</p> <p>Note that this should be emitted as soon as the CM has been notified of the switch, and has updated its internal state. The CM MAY still be in the process of connecting to the new service point.</p>

proxy :

A TpChannel or subclass

callback :

Callback to be called when the signal is received

user_data :

User-supplied data for the callback

destroy :

Destructor for the user-supplied data, which will be called when this signal is disconnected, or before this function returns NULL

weak_object :

A GObject which will be weakly referenced; if it is destroyed, this callback will automatically be disconnected

error :

If not NULL, used to raise an error if NULL is returned

Returns :

a TpProxySignalConnection containing all of the above, which can be used to disconnect the signal; or NULL if the proxy does not have the desired interface or has become invalid.
