💅 IBGTS(3) — Traditional API Functions

okay bestie, gather round, because we're about to talk about ibgts from the linux-gpib fam 🦋 this is a real one, iykyk

✨ NAME ✨

ibgts — release ATN (board) 🎀

like, that's the whole vibe. it releases ATN. periodt.

🌸 SYNOPSIS 🌸

#include <gpib/ib.h>

int ibgts(int ud, int shadow_handshake);

👑 DESCRIPTION 👑

so <pink>ibgts()is literally the *complement* ofibcac()— they're giving opposite-energy siblings fr fr 💫 what it does is it makes the board that your board descriptorud` points to go into standby, and it does that by releasing the ATN line.

⚠️ important lore: the board must be controller-in-change to change the state of the ATN line. no controller-in-change, no ATN changes. that's just the rules, bestie 💀

now here's the tea with shadow_handshake ☕ if it's nonzero, then the board is gonna handshake any data bytes it receives — and it keeps doing that until one of these three things happens:

  1. it hits an EOI
  2. it hits an end-of-string character
  3. the ATN line is asserted again

and the data it receives? discarded. thrown away. not your problem anymore 🙈 the board is just out here catching bytes and dropping them like they're hot 🔥

okay real talk though, ngl: it is generally not necessary to call ibgts(). she's not for everyone. she's provided for advanced users who want direct, low-level access to the GPIB bus — the kind of main character who talks to hardware with no middleman 😤💅

💖 RETURN VALUE 💖

the value of ibsta gets returned. that's it, that's the return value, slay ✨
