__GNU_CXX::_CHAR_TYPES(3cxx)

💜 __gnu_cxx::_Char_types< _CharT > — the libstdc++ manual page, bestie edition

okay so you opened the 3cxx manual page for __gnu_cxx::_Char_types< _CharT > and now you're here. welcome. this is literally the "mapping from character type to associated types" situation, and honestly? it's giving foundational. let's get into it 🫶

✨ NAME ✨

__gnu_cxx::_Char_types< _CharT > — mapping from character type to associated types. that's the whole job. that's the assignment. 💅

---

🦋 SYNOPSIS 🦋

#include <char_traits.h>

🌸 Public Types 🌸

• typedef unsigned long int_type — the int_type. it's unsigned long. iconic, no notes. ⭐
• typedef std::streamoff off_type — the off_type, which is std::streamoff. slay.
• typedef std::streampos pos_type — the pos_type, which is std::streampos. periodt.
• typedef std::mbstate_t state_type — the state_type, which is std::mbstate_t. and that's the whole set 💖

🧚 Detailed Description 🧚

template<typename _CharT>
    struct __gnu_cxx::_Char_types< _CharT >

"Mapping from character type to associated types."

that's the struct's actual tagline btw, not me being extra (for once).

okay so listen 👑 — this is a template struct, template<typename _CharT>, and it maps a character type to its associated types. very much a matchmaker. very "you're a char, and these are your types, go thrive together" energy. 💞

💀 Note (read this one, fr fr)

this is an implementation class for the generic version of char_traits. it defines int_type, off_type, pos_type, and state_type.

by default, those are:

• int_type → unsigned long
• off_type → streamoff
• pos_type → streampos
• state_type → mbstate_t

and here's the tea 🍓: if you need a different set of types, but you don't need to change the definitions of any function defined in char_traits, you can specialize __gnu_cxx::_Char_types while leaving __gnu_cxx::char_traits alone. like, hands off. don't touch it. let it live its life. 🦋

this is the swap the type map, not the whole traits class move. keep it clean, bestie. ✨

that's the page, bestie — libstdc++, <italic>__gnu_cxx::_Char_types< _CharT >(3cxx)</italic>, and this whole vibe lives in the libstd corner of the manual. go forth and map your character types responsibly. mwah 💋 💜
