v4l2_ctrl_type_op_equal(9)

💖 v4l2_ctrl_type_op_equal(9) — your Kernel API Manual bestie 💖

✨ NAME ✨

okay so v4l2_ctrl_type_op_equal is literally the default v4l2_ctrl_type_ops equal callback. That’s the whole name vibe, bestie — no plot twist.

💅 SYNOPSIS 💅

bool v4l2_ctrl_type_op_equal (const struct v4l2_ctrl *ctrl , union
       v4l2_ctrl_ptr ptr1 , union v4l2_ctrl_ptr ptr2 );

🫶 ARGUMENTS 🫶

• ctrl — The v4l2_ctrl pointer. Main-character pointer energy.
• ptr1 — A v4l2 control value. One value in the compare duo.
• ptr2 — A v4l2 control value. The other value, periodt.

🌈 RETURN 🌈

true if values are equal, otherwise false. That’s it — equal means true, not equal means false, no cap.
