add_replay_bud(9)

💅 add_replay_bud — the kernel API manual, but make it a group chat

okay so bestie, welcome to the add_replay_bud page from the Kernel API Manual, section (9). it's giving "small function, big UBIFS energy" and honestly? we're obsessed. let's get into it 🫶

---

✨ NAME ✨

add_replay_bud — literally just adds a bud to the list of buds to replay. that's the whole vibe. no cap. 🌸

---

🎀 SYNOPSIS 🎀

int add_replay_bud (struct ubifs_info *c , int lnum , int offs , int
jhead , unsigned long long sqnum );

look at her. five arguments, one int return, main character energy fr fr 💅

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. she's the context, she's the moment, she's everything 🧚
• lnum — the bud logical eraseblock number to replay. yes, the bud. the one we're replaying. keep up 💖
• offs — the bud start offset. where the bud begins, bestie ✨
• jhead — the journal head to which this bud belongs. every bud's gotta know its jhead, iykyk 👑
• sqnum — the reference node sequence number. numbers, but make it lore ⭐

---

🌈 DESCRIPTION 🌈

so here's the tea ☕ — this function returns zero in case of success, and a negative error code in case of failure.

that's it. that's the description. short, sweet, and absolutely iconic. success = 0, failure = negative error code, and you WILL be checking the return value, bestie. no skipping the vibe check on that one 💀
