smk_write_syslog(9)

💖 smk_write_syslog(9) — like, the write() for smackfs/syslog, bestie 💖

okay so real talk, this page lives in the Kernel API Manual (that's the (9) vibe, kernel-internals girlies rise) and it's all about smk_write_syslog. It's the write() handler for smackfs/syslog and honestly it's giving short-and-sweet, which we love for it. 🎀

---

✨ SYNOPSIS ✨

ssize_t smk_write_syslog (struct file *file , const char __user *buf ,
       size_t count , loff_t *ppos );

that's the whole signature bestie, no cap 🫶

---

🌸 ARGUMENTS 🌸

• file — the file pointer. And the way that it is *not actually used*… iconic honestly, it's just there for the vibes 💅
• buf — where the data comes from. that's the snack source 🍓
• count — how many bytes got sent 📏
• ppos — where to start reading from 👑

---

🦋 DESCRIPTION 🦋

So what does it do? It returns the number of bytes written, or an error code, as appropriate. That's it. That's the whole description. lowkey obsessed with the efficiency ngl ✨

fr fr, "as appropriate" is doing a lot of heavy lifting here — sometimes it's bytes, sometimes it's an error, and the function decides which one is the moment 💀
