FGETWS(3P)

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

okay so this page lives in the POSIX Programmer's Manual, and I need you to hear me on this one thing before anything else: the Linux implementation of this interface may differ (so like, go consult the corresponding Linux manual page for details on Linux behavior, mwah), or honestly the interface might not even be implemented on Linux at all. vibe check first, always. 🫶

✨ PROLOG ✨

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

🎀 NAME 🎀

fgetws — get a wide-character string from a stream 💅

---

🌸 SYNOPSIS 🌸

#include <stdio.h>
#include <wchar.h>

wchar_t *fgetws(wchar_t *restrict ws, int n,
    FILE *restrict stream);

---

🦋 DESCRIPTION 🦋

So the functionality described on this reference page is aligned with the ISO C standard. And like, any conflict between the requirements described here and the ISO C standard is unintentional — not me starting drama on purpose, I promise 😭. This volume of POSIX.1‐2017 defers to the ISO C standard, periodt.

The fgetws() function shall read characters from the stream, convert these to the corresponding wide-character codes, place them in the wchar_t array pointed to by ws, until n-1 characters are read, or a <newline> is read, converted, and transferred to ws, or an end-of-file condition is encountered. Then — and this is the iconic part — the wide-character string, ws, shall be terminated with a null wide-character code. 💖

If an error occurs, the resulting value of the file position indicator for the stream is unspecified. so like, don't come for me, I don't know either 🙈.

The fgetws() function may mark the last data access timestamp of the file associated with stream for update. The last data access timestamp shall be marked for update by the first successful execution of fgetwc(), fgetws(), fwscanf(), getwc(), getwchar(), vfwscanf(), vwscanf(), or wscanf() using stream that returns data not supplied by a prior call to ungetwc(). 👑

---

⭐ RETURN VALUE ⭐

Upon successful completion, fgetws() shall return ws. slay. 🎉

If the end-of-file indicator for the stream is set, or if the stream is at end-of-file, the end-of-file indicator for the stream shall be set and fgetws() shall return a null pointer. 💀

If a read error occurs, the error indicator for the stream shall be set, fgetws() shall return a null pointer, and shall set errno to indicate the error. yeah. it's giving "something went wrong bestie." 😭
