。 recursive_mutex類是一個同步原語，可用於保護共享數據被同時由多個線程訪問.
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提供獨特的，遞歸的所有權語義。
Original:
recursive_mutex offers exclusive, recursive ownership semantics:

  • 。
調用線程「擁有」一個recursive_mutex了一段時間，開始時，它成功地調用函數lock或try_lock。在此期間，該線程可能再次調用lock或try_lock。所有權的周期結束時，線程進行匹配的調用次數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.

  • 。當一個線程擁有一個recursive_mutex，所有其他線程將阻止（調用lock），或者如果他們試圖宣稱擁有的false收到try_lock返回值（為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.

  • 。 ，recursive_mutex可能會被鎖定的最大數量是不確定的，但達到這個數字後，調用lock將拋出std::system_error和調用try_lock將返回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.

程序的行為是不確定的，如果一個recursive_mutex被破壞，同時還擁有由某個線程。 recursive_mutex類是不可複製的。
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.
