sbitmap_get(9)

🎀 NAME 🎀

okay so welcome to the sbitmap_get(9) page from the Kernel API Manual — this one is literally sbitmap_get: try to allocate a free bit from a &struct sbitmap. That’s the whole name vibe, bestie. ✨

✨ SYNOPSIS ✨

int sbitmap_get (struct sbitmap *sb );

💅 ARGUMENTS 💅

• sb — the bitmap you’re allocating from. That’s it. That’s the arg. 🫶

🌸 DESCRIPTION 🌸

The tea: this operation provides acquire barrier semantics if it succeeds. No cap, that’s the whole description. 💖

🔥 RETURN 🔥

If it’s successful, you get a non-negative allocated bit number. Otherwise? -1. Boom. 💀
