tnc_next(9)

💖 tnc_next(9) — from the Kernel API Manual 💖

okay bestie, this is the page for tnc_next(9), and it’s giving kernel-internals main character energy. ✨

🌸 NAME 🌸

tnc_next — find next TNC entry. That’s literally the assignment, no cap. 💅

✨ SYNOPSIS ✨

int tnc_next (struct ubifs_info *c , struct ubifs_znode **zn , int *n );

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. It’s the context bestie, okay?
• zn — the znode. You pass it in, and it gets passed and returned here. 🫶
• n — the znode branch slot number. Also passed in and passed back out right here. ✨

🦋 DESCRIPTION 🦋

okay so the vibe check is simple: this function returns 0 if the next TNC entry is found. If there is no next entry, it returns -ENOENT. Otherwise you get a negative error code. That’s the outcome, periodt. 💖
