UMAD_STATUS(3)

💖 UMAD_STATUS(3) 💖

okay bestie, welcome to the OpenIB Programmer's Manual ✨ this is umad_status(3), and it's literally the vibe check for your umad buffer 🦋

🌸 NAME 🌸

umad_status — get the status of a umad buffer 💅

✨ SYNOPSIS ✨

#include <infiniband/umad.h>

int umad_status(void *umad);

🎀 DESCRIPTION 🎀

So like… umad_status() gets the internal umad status field. that's it, that's the whole job. she's a getter, she's an icon, she's not doing extra 👑

💫 RETURN VALUE 💫

Once a packet has been received, umad_status() returns 0 when the receive was a success, or a non zero status if it was… not that 🙈

ETIMEDOUT means the packet came with a send-timeout indication — clock ran out, no cap. In this case, the transaction ID will be set to the TID of the original request. so yeah, you can still trace it back to where it all started 🕵️♀️
