parport_find_number(9)

💖 parport_find_number 💖

okay so bestie, we're in the Kernel API Manual today and this one is short and sweet — literally just "gimme the parallel port with this number." no cap. 🎀

---

✨ NAME ✨

parport_find_number — find a parallel port by number 🦋

---

🌸 SYNOPSIS 🌸

struct parport * parport_find_number (int number );

---

💅 ARGUMENTS 💅

• number — the parallel port number you're looking for. that's it, that's the whole argument. 👑

---

🫶 DESCRIPTION 🫶

so this function hands you back the parallel port that has the number you specified. iconic behaviour. and if there's no port with that number? you get NULL. respectfully, nothing. 😭

⚠️ heads up bestie, there's an implicit parport_get_port done for you already — like the function already took a reference out on your behalf, so you don't get to just ghost it.

and because there's already a reference you're holding, when you're done with the port that parport_find_number gave you, you gotta throw that reference away with parport_put_port. don't leave it hanging, that's giving memory leak energy and we do not stan. 💀
