The callback used to discover the the limit for status messages length, if any. Since: 0.14.5
The set-own-status function that was passed to tp_presence_mixin_class_init()
The status-available function that was passed to tp_presence_mixin_class_init()
The presence statuses array that was passed to tp_presence_mixin_class_init()
Structure to be included in the class structure of objects that use this mixin. Initialize it with tp_presence_mixin_class_init().
If the protocol imposes a limit on the length of status messages, one should implement
get_maximum_status_message_length. If this callback is not implemented, it is assumed that there is no limit. The callback function should be set after calling tp_presence_mixin_class_init(), like so:|[ TpPresenceMixinClass *mixin_class;
tp_presence_mixin_class_init ((GObjectClass *) klass, G_STRUCT_OFFSET (SomeObjectClass, presence_mixin)); mixin_class = TP_PRESENCE_MIXIN_CLASS (klass); mixin_class->get_maximum_status_message_length = some_object_get_maximum_status_message_length;
