WCSNCAT(3P)

✨ WCSNCAT(3P) ✨ — bestie edition 💖

okay so this one lives in the POSIX Programmer's Manual, and it's giving "the standard wrote this, not your distro." 🫶

🌸 PROLOG 🌸

Real talk: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so like, go read the corresponding Linux manual page for the tea on Linux behavior), or the interface may not even be implemented on Linux at all. 💀

👑 NAME 👑

wcsncat — concatenate a wide-character string with part of another. no cap, that's the whole job. ✨

---

🎀 SYNOPSIS 🎀

#include <wchar.h>

wchar_t *wcsncat(wchar_t *restrict ws1, const wchar_t *restrict ws2,
    size_t n);

---

💅 DESCRIPTION 💅

So the functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional — nobody's trying to start drama. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt. 👑

The wcsncat() function shall append not more than n wide-character codes from the array pointed to by ws2 to the end of the wide-character string pointed to by ws1. and bestie, listen — a null wide-character code and the wide-character codes that follow it are not appended. so if ws2 hits a null early, that's it, we stop. 🛑

The initial wide-character code of ws2 shall overwrite the null wide-character code at the end of ws1. iconic behavior tbh. and a terminating null wide-character code shall always be appended to the result. 💖

⚠️ If copying takes place between objects that overlap, the behavior is undefined. not "kinda weird," not "maybe fine" — undefined. don't do it, bestie. 😭

---

🦋 RETURN VALUE 🦋

wcsncat() shall return ws1. that's it. no return value is reserved to indicate an error — there's no secret error code hiding in there, it's just your string back. 💫

---

🌈 ERRORS 🌈

No errors are defined. none. zero. the void. 🙈

The following sections are informative — aka, the vibe is "we're just chatting now," not "this is normative." 🫶
