libie_debug...ssages_write(9)

🎀 libie_debugfs_nr_messages_write(9) — the Kernel API Manual, bestie edition 💅

okay so you found a page from the Kernel API Manual and it's giving "I write into a debugfs file and I'm lowkey the whole vibe." no cap, this one's short and sweet, so let's go ✨

---

💖 NAME

libie_debugfs_nr_messages_write — the one that writes into the 'nr_messages' file 🫶 literally what it says on the tin.

---

🌸 SYNOPSIS

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

---

🦋 ARGUMENTS

four besties walk into a write call and here's the tea 🍓

• filp — the opened file. it's the file object that got opened, main character energy, the reason you're even here 👑
• buf — where to find the user's data. the payload lives here, and it's coming from userspace so treat it with the respect it deserves 🙈
• count — the length of the user's data. how many bytes of the good stuff 💜
• ppos — file position offset. the little bookmark telling you where we're at 📍
