vb2_core_remove_bufs(9)

💅 vb2_core_remove_bufs — the kernel API manual moment

okay so first things first: this page lives in the Kernel API Manual section 9, and its whole name is literally vb2_core_remove_bufs(9). Bookmark it, bestie. 🎀

✨ NAME ✨

vb2_core_remove_bufs — and ngl the description field here is just… empty? Like the manpage authors said "the name says it all" and clocked out. Iconic of them honestly. The function removes bufs. That's the vibe. 🦋

---

🌸 SYNOPSIS 🌸

int vb2_core_remove_bufs (struct vb2_queue *q , unsigned int start ,
       unsigned int count );

she takes three things and gives you back an int, periodt.

---

💖 ARGUMENTS 💖

girl, here's the whole cast of characters:

• q — a pointer to a struct vb2_queue that's carrying the videobuf2 queue. this is the main character of the story.
• start — the first index of the range of buffers we're about to remove. where the slay begins, basically.
• count — how many buffers we're removing. the size of the little buffer exodus.

---

🔥 RETURN 🔥

returns zero on success 🎉 — and an error code otherwise 😭. that's it. that's the return value. no notes.
