💖 libie_debugfs_log_size_read(9) 💖

okay bestie, so this is a page from the Kernel API Manual (yes, section 9, the kernel-dev section, we love her) and it's all about one tiny little function: libie_debugfs_log_size_read. And what does she do? She reads from the 'log_size' file. That's it. That's the whole vibe. ✨

🌸 NAME 🌸

libie_debugfs_log_size_read — literally just reads from the 'log_size' file, no cap 🎀

---

🦋 SYNOPSIS 🦋

ssize_t libie_debugfs_log_size_read (struct file *filp , char __user
       *buffer , size_t count , loff_t *ppos );

look at her go 💅 four args, one ssize_t return, main character energy fr fr.

---

✨ ARGUMENTS ✨

• filp — the opened file 🗂️ like, the file that's already been opened, bestie.
• buffer — where to write the data for the user to read 📝 this is the spot where the data goes so the user can read it.
• count — the size of the user's buffer 📏 literally how big their buffer is, that's the number.
• ppos — file position offset 📍 the offset of the position in the file.
