Standard library header <stdbit.h> (C++26)
From cppreference.net
Este encabezado estaba originalmente en la biblioteca estándar de C ( <stdbit.h> ).
Este encabezado de compatibilidad con C es parte de la biblioteca de utilidades generales , en particular, proporciona varias plantillas de función para acceder, manipular y procesar bits individuales y secuencias de bits. El orden de bytes (endianness) de los tipos escalares puede inspeccionarse mediante la facilidad __STDC_ENDIAN_NATIVE__ .
No está especificado si <stdbit.h> proporciona alguna declaración en el espacio de nombres std .
