💖 raw_atomic_l...dec_and_test(9) 💖

okay so this is the raw_atomic_l...dec_and_test(9) page, and the manual name is the Kernel API Manual — folded in right here at the top because we're cute and organized. 💅✨

🌸 NAME 🌸

raw_atomic_long_dec_and_test — atomic decrement and test if zero with full ordering. That's the whole assignment, bestie. 🎀

🌈 SYNOPSIS 🌈

bool raw_atomic_long_dec_and_test (atomic_long_t *v );

like, that's the exact signature. no notes. 💖

🫶 ARGUMENTS 🫶

  • v — pointer to atomic_long_t. That's it. That's the argument. She's a pointer, she points at an atomic_long_t, iconic. ✨

💫 DESCRIPTION 💫

Atomically updates v to (v - 1) with full ordering. Yes bestie, atomic, and yes, full ordering — the full-order version, periodt. 🔥

Safe to use in noinstr code; prefer atomic_long_dec_and_test elsewhere. So in noinstr land she's safe, and outside it the manual says prefer atomic_long_dec_and_test, okay? 💅

👑 RETURN 👑

true if the resulting value of v is zero, false otherwise. That's the test part, bestie — the resulting value is zero or it isn't. 💖
