Inicializa el default-construido object objeto atómico con el desired valor. La función no es atómica: el acceso concurrente de otro hilo, incluso a través de una operación atómica, es una carrera de datos .

Original:

Initializes the default-constructed atomic object object with the value desired. The function is not atomic: concurrent access from another thread, even through an atomic operation, is a data race.
