✨ v4l2_m2m_last_dst_buf(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 you're reading the page for v4l2_m2m_last_dst_buf(9), and honestly? it's a little legend. let's get into it 🫶

🌸 NAME 🌸

v4l2_m2m_last_dst_buf — returns the last destination buffer, straight off the list of ready buffers 🎯 yeah. that's the whole vibe.

🦋 SYNOPSIS 🦋

struct vb2_v4l2_buffer * v4l2_m2m_last_dst_buf (struct v4l2_m2m_ctx
*m2m_ctx );

literally one function, one argument, one return type. no cap, minimal queen behavior 👑 and it hands you back a struct vb2_v4l2_buffer *.

🎀 ARGUMENTS 🎀

  • m2m_ctx — the m2m context that's assigned to the instance, the one you get via struct v4l2_m2m_ctx 💅 that's it, that's the whole parameter list, we love a low-maintenance signature.

🌈 SEE ALSO 🌈

like I said. everyone showed up to the party 🧚💜 iykyk.

and that's the page, bestie!! 🎀 this lil beauty lives over in ./include/media, and the version/date on the tin is October 2026 — so go forth, grab that last ready dst buffer, and slay 💅✨
