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

From cppreference.net
C++
Standard library headers

このヘッダーは元々C標準ライブラリに存在していました（ <stdbit.h> ）。

このC互換ヘッダーは 一般ユーティリティ ライブラリの一部であり、特に個々のビットとビットシーケンスへのアクセス、操作、処理を行ういくつかの関数テンプレートを提供します。スカラ型のバイト順序（エンディアン）は __STDC_ENDIAN_NATIVE__ 機能を通じて検査できます。

<stdbit.h> が名前空間 std 内で宣言を提供するかどうかは未規定です。
