UMAD_GET_FD(3)

✨ UMAD_GET_FD ✨

okay bestie, welcome to the OpenIB Programmer's Manual 💖 this one's a lil baby page but it's so useful, i promise. it's umad_get_fd(3), section 3, and it's giving "one job, does it well" energy. 🎀

🌸 NAME 🌸

umad_get_fd — get the umad fd for the requested port 🦋

like. that's it. that's the whole vibe. you want the fd? this is the girl who gives you the fd. slay.

🌈 SYNOPSIS 🌈

#include <infiniband/umad.h>

int umad_get_fd(int portid);

look at her. two lines. no notes. 💅

💜 DESCRIPTION 💜

so umad_get_fd() returns the umad fd for the port specified by portid.

that's the whole thing fr fr. you hand her a portid, she hands you back the umad fd for that port. match made in heaven, no cap. 🫶

👑 RETURN VALUE 👑

umad_get_fd() returns the fd for the portid requested 💚

...or, if you came in there with a portid that's straight-up invalid, she hits you with -EINVAL. 💀 like okay rude but fair. don't be handing her a bogus portid and expecting the fd of your dreams, bestie.

real talk: two outcomes only — a valid fd, or -EINVAL if portid is invalid. that's the vibe check and you either pass or you don't. 🙈
