parport_claim_or_block(9)

💖 NAME 💖

okay bestie, welcome to the parport_claim_or_block(9) page from the Kernel API Manual ✨. This function is literally here to claim access to a parallel port device. That’s the whole vibe. 💅

✨ SYNOPSIS ✨

int parport_claim_or_block (struct pardevice *dev );

🎀 ARGUMENTS 🎀

• dev — a pointer to the structure representing a device on the port 🫶. That’s the thing you pass in so the kernel knows which device wants the port.

🦋 DESCRIPTION 🦋

So here’s the tea ☕: this behaves like parport_claim, but it will block if necessary to wait for the port to be free. No cap, it’s the “wait for it” version. 😭

The return values are giving main character energy, so pay attention 👑:

• return value of 1 — it slept while waiting 😴
• return value of 0 — it succeeded without needing to sleep ⚡
• a negative error code — failure, and that’s the whole story 💀

not me reminding you to check negative return codes — it’s giving basic safety, periodt.
