pc87413_write(9)

💖 NAME 💖

pc87413_write — bestie, the original line is literally pc87413_write -, with the dash and then no description after it. That's the whole NAME situation, no cap 😭🫶

✨ SYNOPSIS ✨

ssize_t pc87413_write (struct file *file , const char __user *data ,
       size_t len , loff_t *ppos );

🎀 ARGUMENTS 🎀

• file — the file handle to the watchdog, aka its lil official pass 💅
• data — the data buffer to write; yes, this is where the bytes go ✨
• len — length in bytes, because we're measuring the payload in bytes around here 🫶
• ppos — pointer to the position to write. No seeks allowed — do not try to scoot around, it's giving "stay put" 😭

🔥 DESCRIPTION 🔥

Okay so a write to a watchdog device is defined as a keepalive signal. That's the vibe. Any write of data will do, as we we don't define content meaning — and yes, the original really says "we we" 😭💀. So don't stress about what the bytes mean; the write itself is the whole point, periodt 💖
