vb2_create_bufs(9)

💅 vb2_create_bufs(9) — a Kernel API Manual moment

okay bestie, buckle up, because we're in the Kernel API Manual today and this one's lowkey a little baddie 🎀

✨ NAME ✨

vb2_create_bufs — it's the wrapper for vb2_core_create_bufs() that also does a vibe check on the memory and type values before anything goes down. no cap, that's its whole thing 💖

🌸 SYNOPSIS 🌸

int vb2_create_bufs (struct vb2_queue *q , struct v4l2_create_buffers
*create );

🦋 ARGUMENTS 🦋

• q — pointer to struct vb2_queue with the videobuf2 queue. yes, the whole queue. she's the main character here 👑
• create — the creation parameters, passed from userspace to the v4l2_ioctl_ops->vidioc_create_bufs handler in the driver. so like, the user's little wishlist gets handed straight to your driver's handler 🌈
