✨ vb2_queue_add_buffer(9) ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> 🫶 — this one's a little function from the videobuf2 squad and honestly it does exactly what it says on the tin. no plot twists. no cap. 💅

💖 NAME 💖

vb2_queue_add_buffer — literally just adds a buffer to a queue. that's it. that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

void vb2_queue_add_buffer (struct vb2_queue *q , struct vb2_buffer *vb ,
       unsigned int index );

notice it returns void? yeah. it's not coming back with a status report, it's just doing the thing. main character energy honestly. ✨

🦋 ARGUMENTS 🦋

• q — pointer to struct vb2_queue with the videobuf2 queue. this is the queue we're sliding stuff into, so like… know your queue, bestie. 👑
• vb — pointer to struct vb2_buffer to be added to the queue. this is the buffer being added, aka the guest of honour arriving at the party. 🎉
• index — index where add vb2_buffer in the queue. yes, that's where it goes. very demure, very mindful, very specific-about-position. 📍

• vb2_queue_remove_buffer(9) — the counterpart, for when a buffer needs to leave the function 🧚 the way they're a matching set fr fr

💀 reminder bestie: this returns void, so don't go checking a return value that does not exist. that's not a vibe check, that's just a compile error. 😭
