vb2_get_plane_payload(9)

💅 vb2_get_plane_payload(9) — Kernel API Manual, bestie edition 🎀

okay so welcome to the Kernel API Manual, and today's main character is vb2_get_plane_payload(9). it's a lil function, it's got one job, and it does it slayfully. let's get into it ✨

---

🌸 NAME 🌸

vb2_get_plane_payload — get bytesused for the plane plane_no

like literally just. tell me how many bytes are used on this plane. that's it. that's the whole vibe. 💖

---

🦋 SYNOPSIS 🦋

unsigned long vb2_get_plane_payload (struct vb2_buffer *vb , unsigned
int plane_no );

note the return type bestie: unsigned long. we're getting a number back, not a struct, not a pointer, a number. love that for us. ⭐

---

👑 ARGUMENTS 👑

• vb — pointer to struct vb2_buffer to which the plane in question belongs to. so like… which buffer are we snooping on? this one. 🫶
• plane_no — plane number for which payload should be set. yes, that plane's number. you gotta know which plane you're asking about, otherwise how is anyone supposed to answer you 😭
