std::char_t...raits::eof,(3)

✨ NAME ✨

okay so bestie, this is the page for std::char_traits::eof from the C++ Standard Libary manual (yes, that spelling is exactly what's on the page, iykyk 🫶). The header is all std::char_t...raits::eof,(3), and the raw NAME block is literally:

std::char_traits::eof,std::char_traits::eof, -
std::char_traits::eof,std::char_traits::eof,

✨ Synopsis ✨

Here's the synopsis in its natural habitat:

std::char_traits<char32_t>::eof

static int_type eof();  (constexpr since C++11)
                        (noexcept since C++11)

The page says: “Returns a value not equivalent to any valid value of type char_type.” That's the whole mood. 😌

And for the general requirements on character traits for X::eof, it says: “See CharTraits for the general requirements on character traits for X::eof.” 💅

✨ Parameters ✨

• (none) — literally no parameters, bestie. Nothing to pass, nothing to flex. 🎀

✨ Return value ✨

Here's the char_type → eof() mapping, and yes it's giving very specific:

• char → EOF
• wchar_t → WEOF
• char8_t → an implementation-defined constant that cannot appear as a valid UTF-8 code unit
• char16_t → an implementation-defined constant that cannot appear as a valid UTF-16 code unit
• char32_t → an implementation-defined constant that cannot appear as a Unicode code point

✨ Complexity ✨

Constant. That's it. That's the complexity. periodt. ⭐

• not_eof — checks whether a character is eof value; [static] (public static member function)

okay that's the whole page, bestie. source: http://cppreference.com, version/date: 2024.06.10, page: std::char_t...raits::eof,(3). mwah 💋✨
