🦋 smk_write_onlycap(9) — Kernel API Manual, bestie edition 🦋

Welcome to the Kernel API Manual, group-chat edition. This page is all about smk_write_onlycap(9), and we are keeping every single detail while making it slay. 💅

💖 NAME 💖

smk_write_onlycap — the write() for smackfs/onlycap. That's the name, and it's lowkey iconic. ✨

🌸 SYNOPSIS 🌸

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

✨ ARGUMENTS ✨

Okay bestie, here's the cast of this function:

• file — file pointer, not actually used. It's giving background-character energy. 💀
• buf — where to get the data from.
• count — bytes sent.
• ppos — where to start.

🔥 DESCRIPTION 🔥

Returns number of bytes written or error code, as appropriate.

That's the whole description — no extra lore, no cap (the pun is right there in onlycap). 😭
