🦋 sscanf(3POSIX) — the POSIX Programmer's Manual, bestie edition 🦋

okay so real talk: this page is part of the POSIX Programmer's Manual ✨ and it's the short one, so we can just hang out for a sec.

✨ PROLOG ✨

okay so before literally anything else, bestie, read this:

  • 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 actual deets on Linux behavior. 👀
  • Or, plot twist, the interface may not be implemented on Linux at all. 😭
not me finding out the hard way that "POSIX says so" and "your kernel does so" are two different vibes. always check both, fr fr.

💖 NAME 💖

sscanf — convert formatted input

like, it takes your string and parses it. icon behavior.

🌸 SYNOPSIS 🌸

#include <stdio.h>

int sscanf(const char *restrict s, const char *restrict format, ...);

so you got your string s (restricted, don't be messy about it), your format (also restricted, respect the contract 🫶), and then ... — the variadic era, the main character energy, all the pointers you're about to fill. 💅

🌈 DESCRIPTION 🌈

Refer to fscanf().

that's it. that's the whole description. the POSIX girlies really said "go read the other page" and honestly? valid. sscanf is just fscanf but the "file" is a string. same format specifiers, same drama, same everything. go read fscanf() for the real tea. 🍓

okay legal moment, no skipping, this all matters:

ngl if you spot a typo it's probably the conversion's fault, not the standard's — snitch to the kernel.org link above and they'll handle it. 💀
