cpu_family man page
cpu_family — Contains the CPU type. Allegro game programming library.
extern int cpu_family;
Contains the Intel type, where applicable. Allegro defines the following CPU family types:
CPU_FAMILY_UNKNOWN - 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
You can read this variable after you have called check_cpu() (which is automatically called by allegro_init()).
check_cpu(3), cpu_vendor(3), cpu_model(3), cpu_capabilities(3), allegro_init(3)
check_cpu(3), cpu_capabilities(3), cpu_model(3), cpu_vendor(3).
