xa_to_value(9)

✨ NAME ✨

xa_to_value(9) — straight from the Kernel API Manual — is the whole “get the value stored in an XArray entry” situation. It’s a tiny getter with main-character energy, and the page is basically like, “here’s how you call it, bestie.” 💖

🌸 SYNOPSIS 🌸

Call it like this, no cap:

unsigned long xa_to_value (const void *entry );

🎀 ARGUMENTS 🎀

• entry — the XArray entry. That’s it. That’s the argument. 🫶

🦋 CONTEXT 🦋

Any context. That’s the entire context vibe check — no extra restrictions listed on this page. ✨

🔥 RETURN 🔥

The value stored in the XArray entry — the unsigned long from the synopsis — comes back to you. That’s the return, periodt. 💅
