✨ pvrdma_query_gid(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — today's main character is pvrdma_query_gid, and honestly? she's a little legend. her whole job is literally just query device gid. that's it. that's the vibe. 🎀

🌸 NAME 🌸

pvrdma_query_gid — query device gid

like… she queries the gid. of the device. no cap, that's the entire plot 🦋

⭐ SYNOPSIS ⭐

int pvrdma_query_gid (struct ib_device *ibdev , u32 port , int index ,
union ib_gid *gid );

she takes four things and gives you back an int, periodt. 💅

🧚 ARGUMENTS 🧚

  • ibdev — the device to query 👑 this is the device you're asking about, she needs to know who she's dealing with
  • port — the port number 🔢 yes, the port number, that's the whole description, don't overthink it
  • index — the index 📇 literally just the index, bestie, it's giving "short and mysterious"
  • gid — the device gid value 💜 this is where the gid value lives

🔥 RETURN 🔥

0 on success 🎉 otherwise a negative errno 😭 (so like, check it, okay? don't just ignore the return value, that's not the energy we're bringing to kernel code)
