add_connection_features

Add features to the desired features to be prepared on Connection objects.

Those features will be added to the features already returned be dup_connection_features.

It is not necessary to add TP_CONNECTION_FEATURE_CORE as it is already included by default.

Note that these features will not be added to existing Connection objects; the user must call prepare_async themself.

Parameters:

this	a SimpleClientFactory object
features	an array of desired features, ending with 0; null is equivalent to an array containing only 0
