💖 TESTSRQ(3) 💖

okay bestie, gather round, because today we're learning about TestSRQ from the gpib library — it's literally just "hey, is the SRQ line vibing or not?" and honestly? iconic. short queen. tiny function. massive main character energy. let's get into it 🫶

✨ NAME ✨

TestSRQ — query the state of the SRQ bus line 🔍

🌸 SYNOPSIS 🌸

#include <gpib/ib.h>

void TestSRQ(int board_desc, short *result);

💅 DESCRIPTION 💅

so TestSRQ() does exactly one thing and she does it flawlessly: it peeks at the state of the SRQ bus line and writes that state to the location that result points at. no cap. that's the whole job. 🎀

here's the decode, bestie:

  • a '1' means the SRQ line is asserted — like, yes, it's up, she's live, she's signaling 🔥
  • a '0' means the line is not asserted — down, quiet, no signal, not today 💤
⚠️ important caveat, don't skip this one: some boards just don't have the range, fr fr. they lack the capability to report the status of the SRQ line at all. when that happens, an ECAP error gets returned in iberr. so if you're getting ECAP vibes, it's not you, it's the board. 😭
