💅 qdio_do_eqbs(9) — Kernel API Manual ✨

okay so bestie, welcome to the qdio_do_eqbs(9) page from the Kernel API Manual — it’s short, it’s specific, and it’s lowkey all about extracting buffer states for QEBSM 🫶

💖 NAME 💖

qdio_do_eqbs — extract buffer states for QEBSM ✨

🦋 SYNOPSIS 🦋

here’s the exact signature, no cap:

int qdio_do_eqbs (struct qdio_q *q , unsigned char *state , int start ,
int count , int auto_ack );

🌸 ARGUMENTS 🌸

• q — the queue to manipulate, periodt.
• state — state of the extracted buffers — yes, literally that 💅
• start — buffer number to start at, bestie.
• count — count of buffers to examine; like, how many are we looking at 👀
• auto_ack — automatically acknowledge buffers, iconic.

✨ DESCRIPTION ✨

It returns the number of successfully extracted equal buffer states. That’s the main-character return value, fr fr.

Processing stops if a state is different from the last buffer’s state — like, the vibe check fails and it stops right there. No cap.
