💖 eurwdt_write(9) 💖

okay bestie, welcome to the Kernel API Manual — this is the page for eurwdt_write(9), and we're gonna get you comfy with it. No cap, it's a short one. 💅

🎀 NAME 🎀

eurwdt_write -

yep, that's the whole NAME line, bestie — no secret subtitle, no extra lore. 😭

✨ SYNOPSIS ✨

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

🫶 ARGUMENTS 🫶

• file — the file handle for the watchdog. 💖
• buf — buffer to write; it's unused here because the data does not matter. 🫠
• count — count of bytes.
• ppos — pointer to the position to write. No seeks allowed — periodt. 🚫

💅 DESCRIPTION 💅

okay so a write to a watchdog device is literally defined as a keepalive signal. Any write of data will do, because we don't define content meaning here — the content is not the main character, the keepalive is. ✨
