upgrade_contacts

Description:

[ Version ( deprecated = true , since = "0.7.18" ) ]
public void upgrade_contacts (Contact[] contacts, ContactFeature[] features, owned ConnectionUpgradeContactsCb callback, Object? weak_object)

Warning: upgrade_contacts is deprecated.

Given several Contact objects, make asynchronous method calls ensure that all the features specified in features are ready for use (if they are supported at all).

Note:

Use upgrade_contacts_async instead.

It is not an error to put features in features even if the connection manager doesn't support them - users of this method should have a static list of features they would like to use if possible, and use it for all connection managers.

Parameters:

this	A connection, which must have the `TP_CONNECTION_FEATURE_CONNECTED` feature prepared
contacts	An array of Contact objects associated with this
features	An array of features that must be ready for use (if supported) before the callback is called
callback	A user callback to call when the contacts are ready
weak_object	An object to pass to the callback, which will be weakly referenced; if this object is destroyed, the operation will be cancelled
destroy	Called to destroy `user_data` either after `callback` has been called, or if the operation is cancelled
n_contacts	The number of contacts in `contacts` (must be at least 1)
n_features	The number of features in `features` (must be at least 1)
user_data	Data to pass to the callback
