smk_read_unconfined(9)

📦 version 7.3.1, in nixpkgs unstable

💖 smk_read_unconfined — from the Kernel API Manual ✨

okay bestie, welcome to the Kernel API Manual 🌸 you're literally reading the page for smk_read_unconfined(9), and yes it's the read() for smackfs/unconfined. She's small, she's iconic, she does one job. Let's get into it 🫶

🌈 SYNOPSIS 🌈

ssize_t smk_read_unconfined (struct file *filp , char __user *buf ,
       size_t cn , loff_t *ppos );

no cap, that's the whole signature 💅

🎀 ARGUMENTS 🎀

  • filp — file pointer, and honestly? not actually used. she's there for the vibes, she's a formality 🙈
  • buf — where to put the result. this is the drop-off spot, the delivery address, the whole point 📦
  • cn — the maximum to send along. cap it, bestie, don't over-share 💀
  • ppos — where to start. your little bookmark in the file 🔖

✨ DESCRIPTION ✨

Returns number of bytes read or error code, as appropriate. that's it, that's the whole description, she's lowkey mysterious and we respect it 👑

fr fr though: it hands you back a byte count on success, or an error code when it's not the moment. no extra lore given here, so we're not inventing any 🌸
