class recursive_mutex;		(dal C++11)

La classe recursive_mutex è una primitiva di sincronizzazione che può essere utilizzato per proteggere i dati condivisi vengano accedere contemporaneamente più thread.

Original:

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

• Un thread chiamante' possiede un recursive_mutex per un periodo di tempo che inizia quando si chiama con successo sia lock o try_lock. Durante questo periodo, il filo potrebbe effettuare chiamate supplementari per lock o try_lock. Il periodo di possesso termina quando il thread fa un numero corrispondente di chiamate a 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.

• Quando un thread possiede un recursive_mutex, tutti gli altri thread si blocca (per le chiamate verso lock) o ricevere un valore restituito false (per try_lock) se tentano di rivendicare la proprietà del 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.

• Il numero massimo di volte che un recursive_mutex possono essere bloccati non è specificato, ma dopo che il numero viene raggiunto, le chiamate a lock lancerà std::system_error e chiama a try_lock tornerà 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.

Il comportamento di un programma non è definito se un recursive_mutex viene distrutto mentre ancora di proprietà di un po 'di filo. La classe recursive_mutex non è copiabile.

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.
