• Un thread appelant' possède une recursive_mutex pendant une période de temps qui commence lors de l'appel avec succès ou l'autre ou locktry_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.

• Le nombre maximum de fois qu'un recursive_mutex peuvent être verrouillés n'est pas spécifié, mais après ce nombre est atteint, les appels à lock jettera std::system_error et appelle à try_lock reviendra false .

  Original:

  The maximum number of times that a recursive_mutex may be locked is unspecified, but after that number is reached, calls to lock will throw std::system_error and calls to try_lock will return false.

Le comportement d'un programme n'est pas défini si un recursive_mutex est détruite alors toujours détenu par un autre thread. La classe recursive_mutex est non copiable .

Original:

The behavior of a program is undefined if a recursive_mutex is destroyed while still owned by some thread. The recursive_mutex class is non-copyable.
