initialize_data_vio(9)

✨ initialize_data_vio(9) ✨

okay so this is a page from the Kernel API Manual, bestie, and it's a short one — but it's lowkey important so pay attention 💅

---

🌸 NAME 🌸

initialize_data_vio — literally allocates all the components of a data_vio. that's it. that's the job 🫶

---

⭐ SYNOPSIS ⭐

int initialize_data_vio (struct data_vio *data_vio , struct vdo *vdo );

---

🎀 ARGUMENTS 🎀

• data_vio — the data_vio you want to initialize. the main character, fr fr 👑
• vdo — the vdo that contains this data_vio. its home base 🏠

---

🦋 DESCRIPTION 🦋

so here's the one thing you actually gotta remember: the caller is responsible for cleaning up the data_vio on error. that's you, bestie. if it goes sideways, the cleanup is your problem, not ours 🙈 don't say we didn't warn you.

---

💜 RETURN 💜

VDO_SUCCESS or an error. slay if it's the first one, cry if it's the second 😭
