iterate_and_advance(9)

💅 iterate_and_advance — Kernel API Manual ✨

okay bestie, welcome to the Kernel API Manual entry for iterate_and_advance(9) — she's giving very specific kernel-iterator energy and we're gonna get into it 🫶

🌸 NAME 🌸

iterate_and_advance — iterate over an iterator. literally that's the whole name, no cap 💖

✨ SYNOPSIS ✨

size_t iterate_and_advance (struct iov_iter *iter , size_t len , void
*priv , iov_ustep_f ustep , iov_step_f step );

🎀 ARGUMENTS 🎀

• iter — the iterator you're iterating over. main character behavior 💅
• len — the amount to iterate over. yes bestie, the length ✨
• priv — data for the step functions. it's giving helper-info 🎀
• ustep — function for UBUF/IOVEC iterators; given __user addresses. user-address vibes 🦋
• step — function for other iterators; given kernel addresses. kernel-address vibes 🌸

🦋 DESCRIPTION 🦋

okay so here's the tea: this is literally just like iterate_and_advance2, but priv2 is always NULL. that's it, that's the whole description — no extra lore, no cap 😭💖

🌈 SEE ALSO 🌈
