Standard library header <stdbit.h> (C++26)

From cppreference.net
C++
Standard library headers

이 헤더는 원래 C 표준 라이브러리에 있었습니다 ( <stdbit.h> ).

이 C 호환성 헤더는 general utility 라이브러리의 일부로, 특히 개별 비트와 비트 시퀀스에 접근, 조작 및 처리를 위한 여러 함수 템플릿을 제공합니다. 스칼라 타입의 바이트 순서(엔디언)는 __STDC_ENDIAN_NATIVE__ 기능을 통해 검사할 수 있습니다.

<stdbit.h> 가 네임스페이스 std 에 어떤 선언을 제공하는지는 명시되지 않았습니다.
