okay so bestie, we're in the Kernel API Manual, section 9, and this page is serving w1_poll_completion — poll for operation completion, with timeout. yes ma'am. 💅

🌸 NAME 🌸

w1_poll_completion — poll for operation completion, with timeout. periodt. ✨

🦋 SYNOPSIS 🦋

int w1_poll_completion (struct w1_master *dev_master , int tout_ms );

🫶 ARGUMENTS 🫶

• dev_master — the device master of the bus. main character energy fr. 👑
• tout_ms — timeout in milliseconds. the clock is ticking, bestie. ⏳

💖 DESCRIPTION 💖

okay so the vibe is: the device is answering 0's while an operation is in progress, and 1's after it completes. literally the status update of all time. 🫶

Timeout may happen if the previous command was not recognised due to a line noise. lowkey chaotic, highkey useful to know. 😭

🔥 RETURN 🔥

• 0 — OK. slay. ✅
• negative error — timeout. not the slay we were hoping for. 💀
