xa_is_value(9)

💅 xa_is_value — the kernel API manual, but make it make sense ✨

okay so bestie, welcome to xa_is_value(9) — it's a page from the Kernel API Manual and it's literally the shortest little vibe check in the XArray family 🎀

---

🌸 NAME 🌸

xa_is_value — figure out if an entry is a value. that's it. that's the whole job 💖

---

✨ SYNOPSIS ✨

bool xa_is_value (const void *entry );

yep, that's the signature. one argument, returns a bool, no cap 🫶

---

🦋 ARGUMENTS 🦋

• entry — an XArray entry. that's the thing you're checking, bestie 💅

---

🧚 CONTEXT 🧚

Any context. literally any. go off 👑

---

⭐ RETURN ⭐

True if the entry is a value, false if it is a pointer. two outcomes, no in-between, main character energy only 🌈
