    • Un thread appelant' possède une recursive_mutex pendant une période de temps qui commence lors de l'appel avec succès ou l'autre ou lock try_lock. Pendant cette période, le fil peut passer des appels supplémentaires pour lock ou try_lock. La durée de détention prend fin lorsque le thread effectue un nombre correspondant d'appels à unlock .
      Original:
      A calling thread owns a recursive_mutex for a period of time that starts when it successfully calls either lock or try_lock. During this period, the thread may make additional calls to lock or try_lock. The period of ownership ends when the thread makes a matching number of calls to unlock.

    • Quand un thread possède un recursive_mutex, tous les autres threads va bloquer (pour les appels vers lock) ou de recevoir une valeur de retour false (pour try_lock) s'ils tentent de revendiquer la propriété de la recursive_mutex .
      Original:
      When a thread owns a recursive_mutex, all other threads will block (for calls to lock) or receive a false return value (for try_lock) if they attempt to claim ownership of the recursive_mutex.
