compare_dents(9)

💅 compare_dents(9) — like, the kernel API manual, but make it make sense 🎀

okay so bestie, welcome to compare_dents(9) from the Kernel API Manual ✨ this one is short but she is mighty, and honestly? she's giving comparator-core 💖

---

🌸 NAME 🌸

compare_dents — compares directory entries by their hash value, no cap 🔥

---

✨ SYNOPSIS ✨

int compare_dents (const void *a , const void *b );

that's it. that's the whole signature. she's compact, she's iconic, she's literally two const void * besties and an int 👑

---

🦋 ARGUMENTS 🦋

• a — the first dent 🍓
• b — the second dent 🌸

two dents, one comparison, main character energy all around 💅

---

💜 DESCRIPTION 💜

so when you're comparing the hash entries of a to b, here's the whole vibe check 👇

• gt (greater than, iykyk) → returns 1 🔥
• lt (less than, we've all been there) → returns -1 😭
• eq (equal, twin flame behaviour) → returns 0 🫶

that's literally it bestie — it's a comparator, she compares, she returns, she leaves. periodt ✨
