std::latch
constexpr explicit latch ( std:: ptrdiff_t expected ) ;
(1) (desde C++20)
latch ( const latch & ) = delete ;
(2) (desde C++20)
1) Construye un latch e inicializa su contador interno. El comportamiento es indefinido si expected es negativo o mayor que max() .
2) El constructor de copia está eliminado. latch no es copiable ni movible.

Parámetros

expected - el valor inicial del contador interno

Excepciones

No lanza nada.
