FIDO_STRERR(3)

💖 FIDO_STRERR 💖

okay bestie, welcome to fido_strerr from section 3 of the Library Functions Manual — she's a lil library function and she's here to translate your Ls into actual words 🫶

✨ NAME ✨

fido_strerr — FIDO2 error codes, but make it readable 💅

🌸 SYNOPSIS 🌸

#include <fido.h>

const char *
fido_strerr(int n);

🦋 DESCRIPTION 🦋

so like. the fido_strerr() function takes the error code n and translates it into a readable string, okay?? it's giving translator, it's giving interpreter, it's giving "your code is screaming and we're putting it into words" 😭

and where does n come from, you ask? n is an error code defined in <fido/err.h>. that's the vibe. that's the source. iykyk 📖✨

now here's the part that matters, so pay attention bestie 👑

• fido_strerr() never returns NULL. never ever. not once. no cap. so you can stop doing the paranoid null check, she's not gonna ghost you 💖
• the returned pointers point to static strings. so like, don't go freeing them, don't go mutating them, just... look at them and appreciate them 🌈
