🎀 GETWC(3P) — POSIX Programmer's Manual 🎀

okay bestie, we're in the POSIX Programmer's Manual rn, and this lil page is all about getwc — she's the one who grabs a wide character off a stream for you 💖

✨ PROLOG ✨

so like, this manual page is part of the POSIX Programmer's Manual. and here's the tea: the Linux implementation of this interface may differ — if you're on Linux, go peek at the corresponding Linux manual page for the actual Linux behavior, mkay? or honestly the interface might just not be implemented on Linux at all. no cap, that's a real possibility. 💀

🌸 NAME 🌸

getwc — get a wide character from a stream ✨

🦋 SYNOPSIS 🦋

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

wint_t getwc(FILE *stream);

💅 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? unintentional, bestie. this volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

the getwc() function shall be equivalent to fgetwc(), EXCEPT — and this is the important part — if it is implemented as a macro, it may evaluate stream more than once. so like… the argument should never be an expression with side-effects. fr fr. 🙈

⭐ RETURN VALUE ⭐

refer to fgetwc(). that's it. she's passing the buck, respectfully 💅

🔥 ERRORS 🔥

refer to fgetwc().

the following sections are informative. iykyk.

🌈 EXAMPLES 🌈

none. 😭 not a single one. we move.

🍓 APPLICATION USAGE 🍓

since it may be implemented as a macro, getwc() may treat a stream argument with side-effects incorrectly. in particular:

getwc(*f++)

does not necessarily work as expected. so therefore… use of this function is not recommended. bestie, just use fgetwc() instead. i'm literally begging you. 🫶

🧚 RATIONALE 🧚

none.

👑 FUTURE DIRECTIONS 👑

none.
