property_entries_dup(9)

🎀 property_entries_dup — the kernel API manual, bestie edition 🎀

okay so real talk, this one's from the Kernel API Manual (yes, property_entries_dup(9) — the (9) is giving kernel-internals realness 💅). it's short, it's sweet, and it deep copies property arrays. let's get into it ✨

---

✨ NAME ✨

property_entries_dup — duplicate an array of properties 🫶

like, it makes a whole new copy. no sharing, no borrowing, no "i'll give it back i promise". a full duplicate, bestie.

---

🌸 SYNOPSIS 🌸

struct property_entry * property_entries_dup (const struct property_entry *properties );

that's the whole signature. look at her. iconic. 👑

---

🦋 ARGUMENTS 🦋

• properties — the array of properties to copy 💖 (this is the thing you're duplicating, so hand her over)

---

⭐ DESCRIPTION ⭐

so what this function does is it creates a deep copy of the given NULL-terminated array of property entries.

read that again: deep copy. not "here's a pointer to the same stuff" shallow nonsense — an actual deep copy, of a NULL-terminated array of property entries. the NULL-terminator part matters, that's how she knows where the array ends, iykyk 🌈

like yes it's one sentence in the original but it's a load-bearing one. deep copy. NULL-terminated. array of property entries. we love a function that knows exactly what it is 🎀

ngl there's not much else on this page, so if you were waiting for a plot twist... there isn't one. she's a small function with a big job. 💜
