Connection Balance interfaceConnection Balance interface — client-side wrappers for the Balance interface |
In some real-time communication services the user can pay for certain services, typically calls to the PSTN, in advance. In (at least) Skype, it's possible to query the current balance in a machine-readable way.
This section documents the auto-generated C wrappers for the Balance interface, used with TpConnection objects.
TpProxySignalConnection * tp_cli_connection_interface_balance1_connect_to_balance_changed (TpConnection *proxy,tp_cli_connection_interface_balance1_signal_callback_balance_changed callback,gpointer user_data,GDestroyNotify destroy,GObject *weak_object,GError **error);
Connect a handler to the signal BalanceChanged.
<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Emitted when the user's balance has changed.</p>
proxy |
A TpConnection 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 |
|
weak_object |
A GObject which will be weakly referenced; if it is destroyed, this callback will automatically be disconnected |
|
error |
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.
void (*tp_cli_connection_interface_balance1_signal_callback_balance_changed) (TpConnection *proxy,const GValueArray *arg_Balance,gpointer user_data,GObject *weak_object);
Represents the signature of a callback for the signal BalanceChanged.
