+### afb_event_name
+
+```C
+/**
+ * Gets the name associated to 'event'.
+ *
+ * @param event the event whose name is requested
+ *
+ * @return the name of the event
+ *
+ * The returned name can be used until call to 'afb_event_unref'.
+ * It shouldn't be freed.

+
+### afb_event_unref
+
+```C
+/**
+ * Decrease the count of references to 'event'.
+ * Call this function when the evenid is no more used.
+ * It destroys the event_x2 when the reference count falls to zero.
+ *
+ * @param event the event
+ */

+## Pushing functions
+
+### afb_event_broadcast
+
+```C
+/**
+ * Broadcasts widely an event of 'event' with the data 'object'.

+ *
+ * For convenience, the function calls 'json_object_put' for 'object'.
+ * Thus, in the case where 'object' should remain available after
+ * the function returns, the function 'json_object_get' shall be used.
+ *
+ * @param event the event to broadcast
+ * @param object the companion object to associate to the broadcasted event (can be NULL)
+ *
+ * @return the count of clients that received the event.

+ * Pushes an event of 'event' with the data 'object' to its observers.
+ * 'object' can be NULL.
+ *
+ * For convenience, the function calls 'json_object_put' for 'object'.
+ * Thus, in the case where 'object' should remain available after
+ * the function returns, the function 'json_object_get' shall be used.
+ *
+ * @param event the event to push
+ * @param object the companion object to associate to the pushed event (can be NULL)
