get_dvsec_vendor0(9)

okay bestie, welcome to get_dvsec_vendor0(9) — the manual page where we go find a related PCI device, function 0 edition. let’s get into it 💅✨

🌸 NAME 🌸

get_dvsec_vendor0 — find a related PCI device (function 0) 🎀

✨ SYNOPSIS ✨

int get_dvsec_vendor0 (struct pci_dev *dev , struct pci_dev **dev0 , int
       *out_pos );

🦋 ARGUMENTS 🦋

• dev — the PCI device to match 🔍
• dev0 — the PCI device (function 0) that gets found 👑
• out_pos — the position of the PCI device (function 0) 📍

💖 DESCRIPTION 💖

okay so the whole vibe is the return value: it returns 0 on success, and negative on failure. that’s literally it, no cap 😭💅

⚠️ NOTE ⚠️

if it’s successful, the reference of dev0 is increased. so after using it, the callers must call pci_dev_put to give up the reference. don’t leave that reference hanging, bestie 🫶🔥
