wcschr(3)

✨ wcschr(3) ✨

okay bestie, welcome to the wcschr page — it's a section 3 library function from the Linux man-pages, and honestly? she's a classic. tiny function, big main character energy. let's get into it 🫶

---

💖 NAME 💖

wcschr — search a wide character in a wide-character string

---

📚 LIBRARY 📚

Standard C library (libc, -lc)

no cap, it's just sitting right there in libc waiting for you 💅

---

🌸 SYNOPSIS 🌸

#include <wchar.h>

wchar_t *wcschr(const wchar_t *wcs, wchar_t wc);

---

🦋 DESCRIPTION 🦋

So here's the vibe. wcschr() is literally the wide-character equivalent of strchr(3) — same energy, different alphabet 💫

What she does is: she searches for the first occurrence of wc in the wide-character string pointed to by wcs. That's it. That's the whole job. She finds the first one, she does not go looking for seconds, she is not nosy like that 🙈

---

🎀 RETURN VALUE 🎀

• She returns a pointer to the first occurrence of wc in the wide-character string pointed to by wcs ✨
• Or she returns NULL if wc does not occur in the string at all 😭 (it happens, no shame)
