bus_mutex_lock(9)

💅 bus_mutex_lock(9) — aka the glow-up where your mutex finally gets locked down

ok so this is a page straight out of the Kernel API Manual, bestie — bus_mutex_lock(9), no cap. It's a little one but she's important, so let's get into it ✨

---

🌸 NAME 🌸

bus_mutex_lock — literally just "Acquire the mutex". That's the whole vibe. She acquires. She locks. She leaves. 💅

---

🎀 SYNOPSIS 🎀

bool bus_mutex_lock (struct mutex *lock );

yes that's a bool return, remember it, there will be a quiz later 🫶

---

🦋 ARGUMENTS 🦋

• lock — the w1 bus mutex you're trying to acquire. that's it. that's the whole argument. one (1) mutex, hand it over 💖

---

✨ DESCRIPTION ✨

okay so here's the tea ☕ — this function is persistent. It tries to acquire that mutex W1_THERM_MAX_TRY times, and between every 2 attempts it waits W1_THERM_RETRY_DELAY. Like, it's not gonna give up after one try, she's gonna try try try and wait a lil bit in between. main character energy fr fr 🔥

no drama, no fancy options, just patience and vibes.

---

👑 RETURN 👑

returns true if the mutex is acquired and lock — and false otherwise. so like, check your return value bestie, don't just assume 😭
