💖 IBIST(3) 💖

okay bestie, we're deep in the Traditional API Functions section of the linux-gpib docs and this one is short but so cute. it's ibist, and yes it's a function name, not a vibe, but honestly? both.

✨ NAME ✨

ibist — set individual status bit (board). that's it. one job. iconic behavior. 👑

🌸 SYNOPSIS 🌸

#include <gpib/ib.h>

int ibist(int ud, int ist);

like two args, one includes, very demure, very mindful. 🎀

🦋 DESCRIPTION 🦋

so here's the tea ☕ — you call ibist and it messes with the individual status bit of a board, and which board? the one you point at with the board descriptor ud. that's your target, no cap.

and then it's all about ist:

  • if ist is nonzero → the individual status bit of the board specified by the board descriptor ud is set ✨
  • if ist is zero → the individual status bit is cleared 💅

and why do we even care about this little bit, you ask? because it's the one the board sends back in response to parallel polls. that's its whole main character moment fr fr. 🌈

oh and heads up — on success, iberr gets set to the previous ist value. not the new one, the previous one. the way that it just archives the old value for you? obsessed. 😭

⭐ RETURN VALUE ⭐

the value of ibsta is returned. that's the whole bullet. go look at it. it's giving "one line, no notes". 💀
