vb2_core_streamoff(9)

💅 vb2_core_streamoff(9) 💅

okay bestie, welcome to the Kernel API Manual page for vb2_core_streamoff(9) — this is the VB2 stream OFF moment, and yes it's lowkey iconic ✨

🌸 NAME 🌸

vb2_core_streamoff — it implements the VB2 stream OFF logic. periodt 💖

🦋 SYNOPSIS 🦋

int vb2_core_streamoff (struct vb2_queue *q , unsigned int type );

🎀 ARGUMENTS 🎀

• q — pointer to struct vb2_queue with the videobuf2 queue. that's the queue bestie 🫶
• type — type of the queue to be started. For V4L2, this is defined by enum v4l2_buf_type type. keep that exact, no cap 💅

✨ DESCRIPTION ✨

Videobuf2 core helper to implement the VIDIOC_STREAMOFF operation. It is called internally by VB2 by an API-specific handler, like videobuf2-v4l2.h. so yeah, it's not out here doing solo main-character stuff — it gets called internally, iykyk 🌈

💫 RETURN 💫

Returns zero on success; an error code otherwise. that's the whole vibe check: 0 = slay, anything else = error code 😭
