💖 IBFIND(3) 💖

okay bestie so this is a page from the Traditional API Functions part of the linux-gpib manual, and we're talking about ibfind today. buckle up, it's short but it slays 🫶

✨ NAME ✨

ibfind — open a board or device (board or device) 🎀

like. it opens a board. or a device. it's giving helpful honestly

🌸 SYNOPSIS 🌸

#include <gpib/ib.h>

int ibfind(const char *name);

that's it. one include, one function call, we love a minimalist icon ✨

💅 DESCRIPTION 💅

so here's the tea, bestie: ibfind() returns a board or device descriptor based on the information found in the configuration file. it goes and looks up whatever you handed it in name, checks the config file, and comes back with a descriptor. simple as that 💖

heads up! if you don't want ibfind() printing error messages to stderr (which, ngl, is a lot of chatter if things go wrong), set the environment variable IB_NO_ERROR before calling the routine. do it first. not after. it does not work retroactively, periodt 💅

and here's the part that's lowkey freeing: you genuinely do not have to use ibfind(). it's not required. if you want, you can get your device descriptors with ibdev() instead, and the 'board index' — that's the minor number in the configuration file, iykyk — can be used directly as a board descriptor. no lookup needed. main character energy fr fr 👑

👑 RETURN VALUE 👑

  • if it worked out? you get a (non-negative) board or device descriptor. slay 💖
  • if it flops? you get -1. that's the fail indicator, no cap 😭
