VSNPRINTF(3P)

💖 VSNPRINTF(3P) 💖

okay bestie, welcome to the POSIX Programmer's Manual ✨ this one lives in the 3P section, and it's giving very much "the whole stdarg crew formats its output" energy 💅

🌸 PROLOG 🌸

okay so before we even get into it, tiny little heads-up that you need to know 🫶

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the details of Linux behavior, fr fr. Or honestly, the interface may not be implemented on Linux at all 💀 just saying.

👑 NAME 👑

vsnprintf, vsprintf — format output of a stdarg argument list 🌈

✨ SYNOPSIS ✨

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

int vsnprintf(char *restrict s, size_t n,
    const char *restrict format, va_list ap);
int vsprintf(char *restrict s, const char *restrict format,
    va_list ap);

🦋 DESCRIPTION 🦋

okay so here's the thing — you gotta go refer to vfprintf(). that's the main character, these two are literally just the va_list flavored siblings 💜
