💖 smk_write_logging(9) — Kernel API Manual 💖

okay so bestie, we're in the Kernel API Manual today and this page is all about smk_write_logging(9). it's a tiny one, a little baby function, but it's the write() half of /smack/logging, so it matters. iykyk 🎀

✨ NAME ✨

smk_write_logging — literally just the write() for /smack/logging 🦋

---

🌸 SYNOPSIS 🌸

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

---

🎀 ARGUMENTS 🎀

• file — the file pointer. and bestie… it's not actually used. it's there, it's invited to the party, it's just not dancing 🙈
• buf — where to get the data from. the goods live here 💅
• count — bytes sent. how many of them. the number. ⭐
• ppos — where to start. your starting point, your origin story 🌈

---
