💖 GETWCHAR — POSIX Programmer's Manual, section 3P 💖

okay bestie, welcome to getwchar(3P), straight outta the POSIX Programmer's Manual ✨

🌸 PROLOG 🌸

so like, real talk first 🫶 — this manual page is part of the POSIX Programmer's Manual. But heads up: the Linux implementation of this interface may differ (so go consult the corresponding Linux manual page for details on Linux behavior, iykyk), or the interface might not even be implemented on Linux at all. 💀 not every system is gonna have your back here.

✨ NAME ✨

getwchar — get a wide character from a stdin stream 🎀

like. one wide char. from stdin. that's the whole job. iconic behavior honestly.

🦋 SYNOPSIS 🦋

#include <wchar.h>

wint_t getwchar(void);

no arguments, no drama, she just works. 💅

💜 DESCRIPTION 💜

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

The getwchar() function shall be equivalent to getwc(stdin).

that's it. that's the function. it's literally getwc(stdin) in a little outfit. 🎀

🔥 RETURN VALUE 🔥

Refer to fgetwc(). 👑

😭 ERRORS 😭

Refer to fgetwc().

The following sections are informative.

🌈 EXAMPLES 🌈

None. 💀 not a single one. we're on our own out here bestie.

💅 APPLICATION USAGE 💅

okay this one MATTERS, 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. like, wchar_t is not invited to that party. periodt. 💅

so don't be out here stuffing a wint_t into a wchar_t and then acting shocked when the WEOF comparison goes feral. 🙈

🧚 RATIONALE 🧚

None. 🌸 she simply does not elaborate.

⭐ FUTURE DIRECTIONS ⭐

None. 💖 the future is, apparently, unchanged.
