SWPRINTF(3POSIX)

💖 SWPRINTF 💖

okay bestie, welcome to the POSIX Programmer's Manual ✨ this one's a lil page from the POSIX set, and just so you know — the Linux version of this interface might lowkey act different (so go check the matching Linux man page for the tea on Linux behavior), or honestly it might not even be implemented on Linux at all. 🙈

🌸 PROLOG 🌸

so this page is part of the POSIX Programmer's Manual, right? and the Linux implementation of this interface may differ — like, consult the corresponding Linux manual page for the details of Linux behavior, no cap. or the interface may not be implemented on Linux, periodt. 💅

✨ NAME ✨

swprintf — print formatted wide-character output 🦋

🎀 SYNOPSIS 🎀

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

int swprintf(wchar_t *restrict ws, size_t n,
    const wchar_t *restrict format, ...);

like, she's got stdio.h and wchar.h in the house, and she takes a wchar_t *restrict ws, a size_t n, a const wchar_t *restrict format, and then ... — yes the ellipsis is invited, she's a variadic icon. 👑

💜 DESCRIPTION 💜

bestie, for this one you gotta go refer to fwprintf(). that's it. that's the whole vibe. she's the wide-character sibling and fwprintf() is holding all the lore. 🫶
