std::localeconv(3)

💖 std::localeconv 💖

okay bestie, this is the std::localeconv(3) page from the C++ Standard Libary, and it's literally all about snagging the current C locale's formatting rules. no cap, it's short but iconic ✨

---

🌸 NAME 🌸

std::localeconv — std::localeconv 💅

---

✨ Synopsis ✨

Defined in header <clocale> 🎀

std::lconv* localeconv();

The localeconv function obtains a pointer to a static object of type std::lconv, which represents numeric and monetary formatting rules of the current C locale. it's giving "let me check the vibes of your money and numbers" 💸

---

🎀 Parameters 🎀

(none) — zero arguments, bestie 🫶

---

🦋 Return value 🦋

Pointer to the current std::lconv object. that's the whole return vibe ✨

---

🌈 Notes 🌈

Modifying the object you reference through the returned pointer is undefined behavior. 🚨 not me warning you about touching stuff you shouldn't touch 💀

std::localeconv modifies a static object, and calling it from different threads without synchronization is also undefined behavior. so yeah, no chaotic multithreaded drive-by action, bestie 😭

---

💅 Example 💅

// Run this code

#include <clocale>
#include <iostream>

int main()
{
    std::setlocale(LC_ALL, "ja_JP.UTF-8");
    std::lconv* lc = std::localeconv();
    std::cout << "Japanese currency symbol: " << lc->currency_symbol
              << '(' << lc->int_curr_symbol << ")\n";
}

---

⭐ Output: ⭐

Japanese currency symbol: ￥(JPY )
