VSWPRINTF(3POSIX)

💖 VSWPRINTF 💖

okay bestie, so this one is from the POSIX Programmer's Manual — yes, that POSIX, the ✨iconic✨ one. come sit with me, this page is short but it's important. 🎀

🌸 PROLOG 🌸

Real talk first, no cap: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so like, consult the corresponding Linux manual page for details of Linux behavior, bestie. Or… the interface may not be implemented on Linux at all. 💀 So don't come for me if it's not there, okay?

✨ NAME ✨

vswprintf — wide-character formatted output of a stdarg argument list 🦋

🎀 SYNOPSIS 🎀

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

int vswprintf(wchar_t *restrict ws, size_t n,
    const wchar_t *restrict format, va_list arg);

look at that signature. she's serving restrict pointers, she's serving va_list. main character energy, fr fr. 💅

💜 DESCRIPTION 💜

okay so. Refer to vfwprintf().

that's it. that's the description. the way that this manpage literally just said "go read the other one" 😭 — and honestly? valid. go read it, bestie. iykyk. 🫶
