random_get_entropy_fallback(9)

💖 random_get_entropy_fallback(9) 💖

okay bestie, welcome to the Kernel API Manual page for random_get_entropy_fallback(9) — yes, the tiny fallback function that keeps the entropy vibes going 🫶✨

🌸 NAME 🌸

random_get_entropy_fallback — returns the raw clock source value, and it's used by random.c for platforms with no valid random_get_entropy(). it's giving "backup plan but make it iconic" 💅

✨ SYNOPSIS ✨

unsigned long random_get_entropy_fallback (void );

translation: it takes literally nothing and hands back an unsigned long 😌

🎀 ARGUMENTS 🎀

• void — no arguments. that's it. no little extras, no secret params, just vibes 🫶
