💖 WCSCAT — the POSIX girlies' guide to gluing wide strings together 💖

okay so bestie, welcome to wcscat(3POSIX), straight outta the POSIX Programmer's Manual 🫶

🌸 PROLOG 🌸

so like, real talk first: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're on Linux, go peek at the corresponding Linux manual page for the actual tea on Linux behavior. and honestly? the interface might not even be implemented on Linux at all. 💀 it's giving "check before you ship".

✨ NAME ✨

wcscat — concatenate two wide-character strings

(like strcat but the wide-character girlies' version, no cap)

🎀 SYNOPSIS 🎀

#include <wchar.h>

wchar_t *wcscat(wchar_t *restrict ws1, const wchar_t *restrict ws2);

💅 DESCRIPTION 💅

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. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

now the actual vibe: wcscat() shall append a copy of the wide-character string pointed to by ws2 — including the terminating null wide-character code — to the end of the wide-character string pointed to by ws1. 🌈

The initial wide-character code of ws2 shall overwrite the null wide-character code at the end of ws1. so basically ws2 slides in and takes that null's spot. iconic behavior honestly.

⚠️ bestie. If copying takes place between objects that overlap, the behavior is undefined. undefined. not "weird", not "kind of off" — undefined. do not do it. this is not a drill 🙈

🔥 RETURN VALUE 🔥

wcscat() shall return ws1. that's it. that's the whole return value.

and no — no return value is reserved to indicate an error. so don't go checking the return for a lil error code, there isn't one. it just hands you ws1 back and expects you to have handled your business beforehand. 💀
