🌸 NAME 🌸

smk_read_doi — literally the read() for /smack/doi. that's it. that's the whole vibe check 🦋

---

✨ SYNOPSIS ✨

ssize_t smk_read_doi (struct file *filp , char __user *buf , size_t count , loff_t *ppos );

look at her go. iconic signature, no notes 💅

🫶 ARGUMENTS 🫶

• filp — the file pointer. and honestly? she's just here for moral support — not actually used. main character energy but zero lines 😭
• buf — where you put the result. the delivery address, the drop-off spot, the whole point 📦✨
• count — the absolute maximum you're allowed to send along. respect the limit bestie, it's giving boundaries 🌈
• ppos — where to start. your starting position, your origin story, your beginning-of-the-buffer moment ⭐

---

💖 DESCRIPTION 💖

Returns the number of bytes read, or an error code, as appropriate. that's the entire plot fr fr — you read stuff, you get told how much you read, or you get an error and you deal with it 🙈 lowkey simple, highkey essential 👑
