fi_version(3)

💖 fi_version(3) — the Libfabric v2.5.1 glam era 💖

okay bestie, so this is the fi_version page from the Libfabric v2.5.1 manual, and honestly? it's short, it's sweet, it's giving "one job and she does it perfectly." let's get into it 🎀

---

✨ NAME ✨

fi_version — literally just: the version of the library interfaces. that's it. that's the whole assignment 💅

---

🌸 SYNOPSIS 🌸

#include <rdma/fabric.h>

uint32_t fi_version(void);

FI_MAJOR(version)

FI_MINOR(version)

like, look at her. three little lines and a header. iconic. the way she doesn't need a single argument... we love a low-maintenance queen 👑

---

🦋 DESCRIPTION 🦋

so you call this thing — fi_version() — and it hands you back the current version of the library interfaces. no cap ✨

and the version isn't some vague vibe, it's got two parts: a major number and a minor number. and here's the cute part — you don't have to do the math yourself, because you can pull them out of the returned value with the FI_MAJOR() and FI_MINOR() macros 🧚

so: call it, get a number, split it with the macros, know your version. slay, done 💜

---

⭐ NOTES ⭐

ngl this is important: the library may support older versions of the interfaces. so the version you get back isn't necessarily the only version in the building — she's just the current one, and she's got range 🫶

---

🔥 RETURN VALUE 🔥

returns the current library version. periodt. 💀

but wait, the bit-packing lore — the upper 16-bits of the returned value correspond to the major number, and the lower 16-bits correspond with the minor number. so it's all packed into one uint32_t like a little gift box 🎁

bestie if you ever try to eyeball the raw number and guess the version, please just use FI_MAJOR() / FI_MINOR() instead. that's what they're FOR 🙈
