WMEMSET(3P)

💖 WMEMSET(3P) — the POSIX Programmer's Manual, bestie edition 💖

okay so before we even get into it — quick vibe check on where this page even comes from.

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. Fr fr, heads up though: the Linux implementation of this interface may differ (so go consult the corresponding Linux manual page for the deets on Linux behavior), or — plot twist — the interface may not even be implemented on Linux at all. 😭

✨ NAME ✨

wmemset — set wide characters in memory. that's it, that's the whole job. 💅

---

🎀 SYNOPSIS 🎀

#include <wchar.h>

wchar_t *wmemset(wchar_t *ws, wchar_t wc, size_t n);

---

🦋 DESCRIPTION 🦋

Okay 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 — no drama intended, it's just how it is. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

The wmemset() function shall copy the value of wc into each of the first n wide characters of the object pointed to by ws. That's the whole glow-up: you're stamping wc over and over again, n times, starting at ws. ✨

This function shall not be affected by locale, and all wchar_t values shall be treated identically. So the null wide character and wchar_t values not corresponding to valid characters shall not be treated specially — no favorites, no special treatment, everyone's equal here. 👑

If n is zero, the application shall ensure that ws is a valid pointer, and the function shall copy zero wide characters. Like, nothing happens, but your pointer still has to be legit. 🫶

---

💜 RETURN VALUE 💜

The wmemset() functions shall return the value of ws. yes bestie, it just hands you back your own pointer. iconic behavior honestly.

---

and that's the whole page bestie!! shoutout to IEEE/The Open Group, 2017 for publishing this, and this page is literally called WMEMSET(3P) — mwah, go set some wide characters, you got this 💅💖✨
