🌸 rhashtable_walk_peek(9) 🌸

okay so bestie, welcome to the Kernel API Manual ✨ this little cutie lives in the kernel and it's about peeking at your hash table without messing up where you're standing. very demure, very mindful 💅

💖 NAME 💖

rhashtable_walk_peek — return the next object but don't advance the iterator 🫶 like, look but don't touch, yk?

✨ SYNOPSIS ✨

void * rhashtable_walk_peek (struct rhashtable_iter *iter );

🎀 ARGUMENTS 🎀

• iter — hash table iterator 🦋 (this is the little guy doing the walking, iykyk)

💫 DESCRIPTION 💫

So like, this function returns the next object, or NULL when you've hit the end of the table 🌈. That's it, that's the vibe.

It returns -EAGAIN if a resize event occurred ⚠️. And no cap, here's the tea: the iterator will rewind back to the beginning and you may continue to use it 🔥. Not me getting sent back to the start and still being iconic 💀👑
