Defined in header <mutex>
class recursive_mutex;		(a partir do C++ 11)

A classe recursive_mutex é um primitivo de sincronização que pode ser usado para proteger os dados compartilhados de ser acessado simultaneamente por vários segmentos.

Original:

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

• Um segmento chamado' possui um recursive_mutex por um período de tempo que começa quando ele chama com êxito ou lock ou try_lock. Durante este período, a linha poderá fazer chamadas adicionais para lock ou try_lock. O período de posse termina quando o segmento faz um número correspondente de chamadas para 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 um segmento possui um recursive_mutex, todos os outros segmentos irá bloquear (para chamadas para lock) ou receber um valor de retorno false (para try_lock) se tentarem reivindicar a posse do 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.

• O número máximo de vezes que um recursive_mutex pode ser bloqueado não é especificado, mas após esse número é atingido, as chamadas para lock vai jogar std::system_error e chama a try_lock voltará 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.

O comportamento de um programa é indefinido se um recursive_mutex é destruído enquanto ainda pertence por alguma thread. A classe recursive_mutex não é copiável.

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.
