ecryptfs_miscdev_read(9) 🫶✨

Okay bestie, this page lives in the Kernel API Manual — and it's literally the function that formats and sends a message from the queue. No cap. 💅

🌸 NAME 🌸

ecryptfs_miscdev_read — format and send message from queue 💖

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• file — the miscdevfs handle. iconic little handle tbh 🫶
• buf — the user buffer where the next message on the daemon queue gets copied into. ✨
• count — how much space is available in buf. like, the capacity check 💅
• ppos — offset in the file. it's ignored, bestie, don't stress 🙈

🦋 DESCRIPTION 🦋

So what it does: pulls the most recent message from the daemon queue, formats it for being sent via a miscdevfs handle, and copies it into buf. ✨

Then it returns the number of bytes copied into the user buffer. That's the whole vibe. 💖
