WCSRCHR(3P)

✨ WCSRCHR(3P) — the POSIX Programmer's Manual era ✨

ok so bestie, welcome to WCSRCHR(3P), straight out of the POSIX Programmer's Manual. pull up a chair, grab a boba, we're doing wide-character string scanning 💅

---

🌸 PROLOG

real talk before we start: this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ — so like, go check the corresponding Linux manual page for the deets on Linux behavior — or honestly the interface might not even be implemented on Linux at all. 🙈

---

👑 NAME

wcsrchr — wide-character string scanning operation. yes queen, that's the whole name.

---

🎀 SYNOPSIS

#include <wchar.h>

wchar_t *wcsrchr(const wchar_t *ws, wchar_t wc);

---

🦋 DESCRIPTION

so the functionality described on this reference page is aligned with the ISO C standard. if there's any conflict between the requirements described here and the ISO C standard, that conflict is unintentional, no cap. this volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

the wcsrchr() function shall locate the last occurrence of wc in the wide-character string pointed to by ws. 💖

now listen carefully because this part matters: the application shall ensure that the value of wc is a character representable as a type wchar_t and a wide-character code corresponding to a valid character in the current locale. don't skip that, it's giving "i didn't read the requirements" energy if you do. 😭

and the terminating null wide-character code shall be considered to be part of the wide-character string. yep, the \0 counts. iconic behavior tbh.

---

🌈 RETURN VALUE

upon successful completion, wcsrchr() shall return a pointer to the wide-character code — or a null pointer if wc does not occur in the wide-character string. that's it, that's the whole vibe check. 🫶

---

💜 ERRORS

no errors are defined. literally none. slay.

the following sections are informative — meaning they're the bonus content, the director's commentary, if you will.

🍓 EXAMPLES

none. 🙈

---

🧚 APPLICATION USAGE

none. still nothing. we're keeping it minimal bestie.

---

⭐ RATIONALE

none. the rationale said "no thoughts, head empty." 💀

---

💀 FUTURE DIRECTIONS

none. the future is a mystery but this function is not changing, iykyk.
