+ * @beginrst
* It is strictly impossible to use a real mutex, such as
- * std::mutex
- * or pthread_mutex_t,
+ * `std::mutex `_
+ * or `pthread_mutex_t `_,
* because it would block the whole simulation.
- * Instead, you should use the present class, that is a drop-in replacement of
- * ` for memory management of Mutexes.
+ * Use :cpp:func:`create() ` to get a :cpp:type:`simgrid::s4u::MutexPtr` to a newly
+ * created mutex, and only manipulate :cpp:type:`simgrid::s4u::MutexPtr`.
