recursive_mutexクラスは、同時に複数のスレッドによってアクセスされるから共有データを保護するために使用できる同期プリミティブです.
Original:
The recursive_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.

  • 呼び出し元のスレッドそれが正常recursive_mutexまたはlockを呼び出したときに、開始時間の期間のためにtry_lockを所有しています。この期間中、スレッドはlockまたはtry_lockに追加の呼び出しを行うことがあります。スレッドがunlockへの呼び出しのマッチング数を作るときに所有権の期間が終了.
    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.

  • スレッドがrecursive_mutexを所有している場合は、他のすべてのスレッドがブロック(lockへの呼び出しの場合)、または彼らはfalseの所有権を主張しようとした場合try_lockの戻り値を(recursive_mutex用)が表示されます.
    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がロックすることができる最大回数が指定されていないが、その数に達した後、lockをコールするにはstd::system_errortry_lockコールをスローしますfalseを返すでしょう.
    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.

まだいくつかのスレッドが所有している間recursive_mutexが破壊されている場合は、プログラムの動作は未定義です。 recursive_mutexクラスは非コピー可能です.
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.
