UMAD_DEBUG(3)

💖 UMAD_DEBUG(3) — the umad_debug page, bestie edition 💖

okay so this is the manual for umad_debug from the OpenIB Programmer's Manual, and honestly? it's short, it's sweet, it's giving "one tiny function that controls how chatty the library is." 🎀

✨ NAME ✨

umad_debug — set debug level 💅

🌸 SYNOPSIS 🌸

#include <infiniband/umad.h>

int umad_debug(int level);

like. that's the whole vibe. one include, one function, no drama. 🦋

💜 DESCRIPTION 💜

so umad_debug() sets the umad library's internal debug level to level. that's it, that's the job, and it does it flawlessly no cap. ✨

here are the levels it supports, bestie, memorize them:

• 0 — no debug at all. this is the default. silent, mysterious, main character energy. 🤫
• 1 — basic debug info. a lil peek behind the curtain. 👀
• 2 — verbose debug info. she's telling you EVERYTHING. 😭

⚠️ heads up: negative values are ignored in terms of set — so like, don't think you can pass a negative number and change the level, because you literally cannot. 🚫

BUT. and this is the cute lil plot twist: you can query the current debug level by passing a negative value as level. so negatives don't set anything, they just tell you things. it's giving ✨look but don't touch✨. 🔍

👑 RETURN VALUE 👑

umad_debug() returns the actual debug level. so whatever it ends up being, you get it back. she always answers. 🫶
