VA_ARG(3POSIX)

💖 VA_ARG(3POSIX) — bestie edition 💖

okay so this is VA_ARG(3POSIX), and it's living inside the POSIX Programmer's Manual 🎀

🌸 PROLOG (the lil' disclaimer bestie) 🌸

This manual page is part of the POSIX Programmer's Manual. Heads up tho: the Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the deets — or the interface might just... not be implemented on Linux at all. 💀 Yeah. It's giving "read the room before you ship."

✨ NAME ✨

va_arg, va_copy, va_end, va_start — handle variable argument list 🫶

💅 SYNOPSIS 💅

#include <stdarg.h>

type va_arg(va_list ap, type);
void va_copy(va_list dest, va_list src);
void va_end(va_list ap);
void va_start(va_list ap, argN);

Look at that. Four little functions carrying the whole variable-args situation on their backs. 👑

🦋 DESCRIPTION 🦋

Refer to the Base Definitions volume of POSIX.1‐2017, <stdarg.h> 📖

That's it. That's the whole description. Short queen behavior. If you want the actual lore, the <stdarg.h> entry in the Base Definitions volume of POSIX.1‐2017 is where it lives. iykyk 🌈
