ASYNCIBERR(3)

✨ ASYNCIBERR ✨

okay bestie, welcome to AsyncIberr — utility function energy, section 3 of the manual, we're in the <gpib/ib.h> cinematic universe 💅

---

🌸 NAME 🌸

AsyncIberr — the iberr value for ur last asynchronous I/O operation 🦋

---

🎀 SYNOPSIS 🎀

#include <gpib/ib.h>

int AsyncIberr(void);

like. that's it. that's the whole vibe. one call, no args, no drama ✨

---

💖 DESCRIPTION 💖

okay so AsyncIberr() hands u back a thread-local error number, and it's related to the global variable iberr. 🫶

its value corresponds to the result of the last asynchronous I/O operation that got resynchronized to the current thread by an ibwait or ibstop call. periodt.

and here's the part that's actually iconic 👑: this function only reflects the result of the asynchronous I/O operation itself — and NOT, for example, the ibwait that resynchronized the asynchronous result to the current thread. so the AsyncIberr() result is genuinely easier to interpret than ThreadIberr(), because it's unambiguous whether the value is associated with the async I/O result, or with the function call used to resynchronize (ibwait or ibstop). no confusion, no guessing, we love a clean signal 💚

fr fr this function is a Linux-GPIB extension — so if u were looking for it in some other GPIB library, bestie, it's not there 🙈

---

⭐ RETURN VALUE ⭐

u get back a value related to iberr that corresponds to the last asynchronous I/O operation resynchronized to the current thread. that's the tea 🍓
