DEFINE_XARRAY_ALLOC1(9)

💖 DEFINE_XARRAY_ALLOC1(9) 💖

okay so bestie, this is the Kernel API Manual entry for DEFINE_XARRAY_ALLOC1, and it’s giving tiny-but-iconic definition energy. ✨

🌸 NAME 🌸

DEFINE_XARRAY_ALLOC1 — Define an XArray which allocates IDs starting at 1. 💅

✨ SYNOPSIS ✨

DEFINE_XARRAY_ALLOC1 (name );

🎀 ARGUMENTS 🎀

• name — a string that names your XArray. That’s literally the whole argument, bestie. 🫶

🦋 DESCRIPTION 🦋

This is intended for file scope definitions of allocating XArrays. See also DEFINE_XARRAY. That’s the vibe — short, sweet, and very “you already know what to do with it.” 😭
