✨ GETWCHAR(3POSIX) ✨

ok so this is from the POSIX Programmer's Manual, bestie 💖

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. Heads up tho — the Linux implementation of this interface may differ (so like, go check the corresponding Linux manual page for the tea on Linux behavior), or honestly the interface may not even be implemented on Linux at all. 🙈

👑 NAME 👑

getwchar — get a wide character from a stdin stream. that's it, that's the whole job 💅

🎀 SYNOPSIS 🎀

#include <wchar.h>

wint_t getwchar(void);

🦋 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 — like, nobody's trying to start drama. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

The getwchar() function shall be equivalent to getwc(stdin). literally just that, no cap. ✨

💜 RETURN VALUE 💜

Refer to fgetwc(). (yeah bestie, the answers live over there 🫶)

💅 ERRORS 💅

Refer to fgetwc().

The following sections are informative.

🍓 EXAMPLES 🍓

None. (not a single one. it's giving minimalist 😭)

🌈 APPLICATION USAGE 🌈

ok this one's important, listen up 🔥 — if the wint_t value returned by getwchar() is stored into a variable of type wchar_t and then compared against the wint_t macro WEOF, the result may be incorrect. Only the wint_t type is guaranteed to be able to represent any wide character and WEOF. so don't be messy with your types, mkay? 💀

fr fr, wchar_t is NOT the vibe here. only wint_t is guaranteed to hold any wide character AND WEOF. don't do the swap, bestie.

🧚 RATIONALE 🧚

None. (iconic of them honestly, nothing to justify 💖)

⭐ FUTURE DIRECTIONS ⭐

None. (the future is… nothing changing. slay 👑)
