🦋 xa_is_advanced(9) 🦋

okay so bestie, this is the Kernel API Manual page for xa_is_advanced(9) — the tiny vibe check that answers whether an entry is only permitted for the advanced API. it's short, it's iconic, and it's literally one question with a bool answer ✨

💖 NAME 💖

xa_is_advanced — Is the entry only permitted for the advanced API?

✨ SYNOPSIS ✨

bool xa_is_advanced (const void *entry );

🎀 ARGUMENTS 🎀

• entry — Entry to be stored in the XArray. that's the one thing you're handing over, bestie 🫶

🌸 RETURN 🌸

It returns true if the entry cannot be stored by the normal API. so if the entry is giving advanced-only energy, you get true — that's the whole return value, no cap 💅
