VSSCANF(3POSIX)

🌸 PROLOG 🌸

okay bestie, real talk before we get into it: this page is part of the POSIX Programmer's Manual 💖. The Linux implementation of this interface may be different (so if you're on Linux, go check the matching Linux manual page for the tea ☕), or honestly the interface might not even be implemented on Linux at all. no cap. 🙈

👑 NAME 👑

vsscanf — format input of a stdarg argument list

like… it takes a big ol' pile of variable arguments and reads formatted input out of them. slay.

🦋 SYNOPSIS 🦋

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

int vsscanf(const char *restrict s, const char *restrict format,
    va_list arg);

three headers-included things, one function, four params. iconic. ✨

💖 DESCRIPTION 💖

Refer to vfscanf().

that's it. that's the whole description. the POSIX girlies said "go read the other one, it's giving the same energy" and honestly? valid. 🫶 vsscanf is lowkey just the va_list-flavored sibling of that whole family, so the real details live over there. go look. iykyk. 💅
