print_pci_hwpath(9)

💖 print_pci_hwpath(9) — a Kernel API Manual moment 💖

okay so bestie, welcome to the print_pci_hwpath(9) page, straight out of the Kernel API Manual ✨ this one's short and sweet and honestly kind of a serve, so let's get into it 🫶

---

🌸 NAME 🌸

print_pci_hwpath — returns the hardware path for PCI devices, no cap 💅

---

✨ SYNOPSIS ✨

char * print_pci_hwpath (struct pci_dev *dev , char *output );

literally the whole signature, keep it exactly like this ⭐

---

🎀 ARGUMENTS 🎀

• dev — the device you want the path for, that's the main character here 👑
• output — a pointer to an array you already allocated before calling, because this function is not about to allocate anything for you 🙈 the path goes in here.

---

🦋 DESCRIPTION 🦋

so what does it do? it fills in that output array with a human-readable path to a PCI device 💖

and the vibe of that string? it's compatible with the one used by PDC, and it may be printed on the outside of the box 🍓 like yes, it's literally designed to be cute and legible on physical hardware, iykyk 🔥

bestie reminder: output has to be previously allocated by you. this function fills the array, it does not create it. do not come for me if you pass a random pointer 😭
