class recursive_mutex;		(начиная с C++11)

recursive_mutex класс примитив синхронизации, которые могут быть использованы для защиты общих данных от одновременного доступа нескольких потоков.

Original:

The recursive_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.

recursive_mutex предлагает эксклюзивные, рекурсивные семантику владения

Original:

recursive_mutex offers exclusive, recursive ownership semantics:

• Вызывающий поток' владеет recursive_mutex за определенный период времени, который начинается, когда он успешно вызывает либо lock или try_lock. В течение этого периода, нить может сделать дополнительные вызовы lock или try_lock. Период владения заканчивается, когда поток делает соответствующую количество обращений к 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.

• Когда поток владеет recursive_mutex, все остальные потоки будут блокировать (для звонков в lock) или получать значение false возвращение (для try_lock), если они пытаются претендовать на владение 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.

• Максимальное количество раз, что recursive_mutex может быть заблокирован не определен, но после этого число будет достигнуто, призывы к lock будет бросать std::system_error и призывает try_lock вернется 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.

Поведение программы не определено, если recursive_mutex разрушен в то время как до сих пор принадлежит какую-нить. recursive_mutex класс не является копируемой.

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.
