✨ UMAD_SET_ADDR(3) ✨

okay bestie, welcome to the umad_set_addr page from the OpenIB Programmer's Manual 💜 this one's a little baby function but she's important, so let's get into it 🫶

🌸 NAME 🌸

umad_set_addr — set MAD address fields within an umad buffer using host ordering 💅

🎀 SYNOPSIS 🎀

#include <infiniband/umad.h>

int umad_set_addr(void *umad, int dlid, int dqp, int sl, int qkey);

🦋 DESCRIPTION 🦋

so basically, umad_set_addr() sets the MAD address fields inside the umad buffer you hand it, using the host ordered fields you give it. it's giving "fill in the blanks but make it networking" ✨

here's the tea on each arg:

• dlid — the destination LID 🎯
• dqp — the destination QP (that's queue pair, iykyk)
• sl — the SL (service level) 🌈
• qkey — the Q_Key (queue key) 🔑

👑 RETURN VALUE 👑

umad_set_addr() returns 0 on success, and a negative value on errors. and like… currently? there are no errors indicated. so she's lowkey just vibing and always succeeding, periodt 💅✨
