+@brief Adds the listener \p listener to the CTF IR trace class

+
+\p listener is called with \p data, the user data, the first time
+bt_trace_set_is_static() is called on \p trace_class.
+
+When the trace is destroyed, or when you remove the added listener with
+bt_trace_remove_is_static_listener(), \p listener_removed is called
+if it's not \c NULL. You can use \p listener_removed to free any dynamic
+data which exists only for the added listener. You cannot call
+any function which modifies \p trace_class during the execution of
+\p listener_removed, including bt_trace_remove_is_static_listener().
+
+This function fails if \p trace_class is already static: you need to
+check the condition first with bt_trace_is_static().
+
+On success, this function returns a unique numeric identifier for this
+listener within \p trace. You can use this identifier to remove the
+specific listener you added with
+bt_trace_remove_is_static_listener().
+
+@param[in] trace_class Trace class to which to add the
+ listener.
+@param[in] listener Listener to add to \p trace_class.
+@param[in] listener_removed Remove listener called when \p listener
+ is removed from \p trace_class, or
+ \c NULL if you don't need a remove
+ listener.
+@param[in] data User data passed when \p listener or
+ \p listener_removed is called.
+@returns A unique numeric identifier for this
+ listener on success (0 or greater), or a
+ negative value on error.
