cpu_family(3alleg4)

✨ cpu_family ✨

okay bestie, buckle up, this is a page from the Allegro manual (that's the Allegro game programming library, the one and only 👑) and it's about a little global called cpu_family — the variable that knows what kind of CPU you're running on. it's giving ✨hardware detective✨.

🌸 SYNOPSIS 🌸

#include <allegro.h>

extern int cpu_family;

like, that's it. one extern int. she's simple, she's iconic, she's global 💅

💖 DESCRIPTION 💖

so cpu_family contains the Intel type, where applicable — meaning: if your processor is an Intel-ish one, this is where Allegro tells you which flavor. Allegro defines these CPU family types:

• CPU_FAMILY_UNKNOWN — we literally have no idea what processor this is 🙈 the type of processor is unknown
• CPU_FAMILY_I386 — the processor is an Intel-compatible 386
• CPU_FAMILY_I486 — the processor is an Intel-compatible 486
• CPU_FAMILY_I586 — the processor is a Pentium or equivalent
• CPU_FAMILY_I686 — the processor is a Pentium Pro, II, III or equivalent
• CPU_FAMILY_ITANIUM — the processor is an Itanium processor
• CPU_FAMILY_POWERPC — the processor is a PowerPC processor 🦋
• CPU_FAMILY_EXTENDED — the processor type needs to be read from the cpu_model (so like, this one's a plot twist, go check cpu_model for the real answer)

🫶 important lil note bestie: you can only read this variable after you've called check_cpu() — and good news, allegro_init() calls it for you automatically, so you don't even have to think about it. she's got you covered, no cap.

and that's the whole page, bestie 💜 this was Allegro version 4.4.3, dated way back, and the page itself is cpu_family(3alleg4) — k bye, go read check_cpu(3alleg4) next, mwah 🎀✨
