NAME
cpu_model - Contains the Intel CPU submodel. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
extern int cpu_model;
DESCRIPTION
Contains the CPU submodel, where applicable. Allegro defines at least the following CPU family types (see include/allegro/system.h for a more complete list):
CPU_FAMILY_I586:
CPU_MODEL_PENTIUM, CPU_MODEL_K5, CPU_MODEL_K6
CPU_FAMILY_I686:
CPU_MODEL_PENTIUMPRO, CPU_MODEL_PENTIUMII,
CPU_MODEL_PENTIUMIIIKATMAI, CPU_MODEL_PENTIUMIIICOPPERMINE,
CPU_MODEL_ATHLON, CPU_MODEL_DURON
CPU_FAMILY_EXTENDED:
CPU_MODEL_PENTIUMIV, CPU_MODEL_XEON,
CPU_MODEL_ATHLON64, CPU_MODEL_OPTERON
CPU_FAMILY_POWERPC:
CPU_MODEL_POWERPC_x, for x=601-604, 620, 750, 7400, 7450
You can read this variable after you have called check_cpu() (which is automatically called by allegro_init()). Make sure you check the cpu_family and cpu_vendor so you know which models make sense to check.
