IEEE1284_CLAIM(3)

💖 NAME 💖

ieee1284_claim — bestie, it's literally the "lemme have the port real quick" function 💅

It's a libieee1284 thing, from the Functions section of the manual (section 3, for all my iykyk girlies ✨).

---

🌸 SYNOPSIS 🌸

#include <ieee1284.h>

int ieee1284_claim(struct parport *port);

---

🦋 DESCRIPTION 🦋

Okay so listen, this is the ✨main character✨ move of the whole library. Before you do literally anything else with a device on a port, you gotta claim that port first.

The one tiny exception, the single little loophole in the whole vibe: ieee1284_get_deviceid(3). That one gets a pass 🙈. Every other libieee1284 function that touches a device on the port? Nope. You must call ieee1284_claim on an open port first. No claim, no access, no exceptions, periodt. 👑

Real talk though: the port has to be open already. Claiming a port you never opened is not it, and the function will absolutely let you know (see below 👇).

💜 RETURN VALUE 💜

So like, what do you get back? Depends, bestie:

• E1284_OK — Slay!! It worked!! ✨ But heads up: unless you specified the F1284_EXCL flag to start with, you should release the port within a "reasonable" amount of time. Don't be a port hog, it's giving rude 💀
• E1284_NOMEM — Not enough memory. The vibes were not immaculate. 😭
• E1284_INVALIDPORT — the port parameter is invalid. Like... for instance, it might not have been opened yet. Bestie. You have to open it first. 🙈
• E1284_SYS — something went wrong at the operating system level. And when this happens, the global variable errno has been set appropriately, so go peek at it, it's spilling the tea 🫖
