C++ incluye soporte para threads (hilos), exclusión mutua, variables de condición y futuros.

Threads (hilos)

Los hilos permiten a los progamas ejecutar varias ejecuciones en paralelo. Permitiendo así aprovechar los núcleos de un procesador.

Exclusión mutua

Los algoritmos de exclusión mutua permite a varios hilos protegerse del acceso simultaneo a recursos compartidos. Esto permite evitar corrupciones de datos y proporciona bases para la sincronización entre hilos.

Las variables de condición

Una variable de condición es un objeto de sincronización que facilita que múltiples hilos puedan comunicarse entre sí. Permite que algunos hilos esperen (posiblemente con un tiempo máximo de espera) hasta que llegue la notificación de otro hilo para que ellos puedan continuar. Una variable de condición siempre está asociado a un mutex.

Defined in header <condition_variable>
condition_variable (C++11)	provides a condition variable associated with a std::unique_lock (clase)
condition_variable_any (C++11)	provides a condition variable associated with any lock type (clase)

cv_status (C++11)	lists the possible results of timed waits on condition variables (enum)

Futuros

La biblioteca estándar proporciona facilidades para la obtención de los valores que se devuelven y para atrapar las excepciones producidas por tareas asincrónas (es decir, las funciones puestas en marcha por hilos). Estos valores están en un "estado compartido", y de forma asincrona, se le puede poner un retorno o una excepción que será examinada por otros hilos.
