<cerrno>で定義されているマクロのそれぞれがintのほとんどをマッチング、型POSIX error codesを持つ整数定数式で、正の値を持つそれぞれに展開されます。以下の定数が定義されています（実装は、限り、彼らは数字または大文字に続いて'E'で始まるように、よりを定義するかもしれません）
Original:
Each of the macros defined in <cerrno> expands to integer constant expressions with type int, each with a positive value, matching most of the POSIX error codes. The following constants are defined (the implementation may define more, as long as they begin with 'E' followed by digits or uppercase letters)
