## NAME

cpu\_family - Contains the CPU type. Allegro game programming library.

   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
```

You can read this variable after you have called check\_cpu() (which is automatically called by allegro\_init()).
