IBCNT(3)

💖 IBCNT(3) 💖

okay bestie, gather round — this is the ibcnt page from the Linux-GPIB Reference, and honestly? it's a short one but it's kinda iconic. ✨

---

🌸 NAME 🌸

ibcnt — hold number of bytes transferred, or errno 🫶

---

✨ SYNOPSIS ✨

#include <gpib/ib.h>

volatile int ibcnt;
volatile long ibcntl;

---

💅 DESCRIPTION 💅

so here's the tea, bestie 🍓 — ibcnt and ibcntl get set after IO operations to the number of bytes that got sent or received. that's it, that's the job. they be counting. 👑

they also get set to the value of errno after EDVR or EFSO errors. so if something goes feral, check here. 😭

and now for the ✨pro tip✨ section: if you're lowkey not vibing with the whole global variable situation — and honestly, valid, globals are giving 1985 — you can instead use ThreadIbcnt() or ThreadIbcntl(), which return thread-specific values instead. no cap. 🧚

bestie note: the descriptions say "the the the number of bytes" in the original, and I am simply not going to pretend that's normal. but the meaning is clear: it's the byte count. periodt. 💀
