cpu_family(3)

💖 cpu_family(3) 💖

okay bestie, so this is a page from the Allegro manual — the Allegro game programming library, no cap — and today we're talking about cpu_family(3), aka the little variable that knows what kinda brain your processor has. it's giving "who am I" but for silicon. let's go 🦋

✨ NAME ✨

cpu_family — contains the CPU type. part of the Allegro game programming library, obviously 💅

🌸 SYNOPSIS 🌸

#include <allegro.h>

extern int cpu_family;

literally that's it. one #include, one extern int. iconic behaviour.

🎀 DESCRIPTION 🎀

so cpu_family holds the Intel type, where applicable. and Allegro has these whole CPU family types defined for you, bestie, here's the full roster — every single one, don't skip:

• CPU_FAMILY_UNKNOWN — the type of processor is unknown (mystery machine energy, we don't know her 🙈)
• 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 👀

⚠️ important queen: you can only read this variable after you've called check_cpu(). and good news — check_cpu() is automatically called by allegro_init(), so if you did the init thing you're already covered. don't read it before, it will not have your back fr fr 😭

👑 SEE ALSO 👑

• check_cpu(3)
• cpu_vendor(3)
• cpu_model(3)
• cpu_capabilities(3)
• allegro_init(3)

and that's the whole page, bestie, you ate it 💅 this was Allegro, version 4.4.3 — cpu_family(3), the CPU-type lore, delivered with love from the Allegro manual. go read your cpu's mind, but only after check_cpu(). periodt 🫶✨🌸💖
