      Die recursive_mutex Klasse ist ein Synchronisierungsgrundeinheit, die verwendet werden, um gemeinsame Daten aus gleichzeitig von mehreren Threads zugegriffen schützen können .
      Original:
      The recursive_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.

      • Ein aufrufenden Threads' besitzt eine recursive_mutex für eine Zeitspanne, die beim Aufrufen erfolgreich entweder lock oder try_lock beginnt. Während dieser Zeit kann sich der Faden zusätzliche Anrufe lock oder try_lock machen. Der Zeitraum des Besitzes endet, wenn der Thread macht eine passende Anzahl von Anrufen 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.

      • Wenn ein Thread eine recursive_mutex besitzt, werden alle anderen Threads blockieren (für Anrufe in lock) oder erhalten eine false Rückgabewert (für try_lock), wenn sie das Eigentum an der recursive_mutex behaupten versuchen .
        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.

      • Die maximale Anzahl, wie oft ein recursive_mutex gesperrt werden kann, ist unbegrenzt, aber nach, dass Anzahl erreicht ist, werden Anrufe an lock wird std::system_error werfen und ruft try_lock zurückkehren 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.

      Das Verhalten eines Programms ist nicht definiert, wenn ein recursive_mutex zerstört wird, während noch von einem Thread gehört. Die recursive_mutex Klasse ist nicht kopierbar .
      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.
