cpu_model - Man Page

#include <allegro.h>

extern int cpu_model;

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.

check_cpu(3), cpu_vendor(3), cpu_family(3), cpu_capabilities(3), allegro_init(3)

check_cpu(3), cpu_capabilities(3), cpu_family(3), cpu_vendor(3).
