NAME
cpu - Global Variable: Provides a unique logical processor-type family identifier
SYNOPSIS
extern int cpu;
DESCRIPTION
The cpu global variable provides a unique logical family identifier of the processor type of the running system. The logical system name
can represent a single processor or a family of processor types. For example, the constant DEC_3000_500 represents the DEC 3000 Model 500
Alpha Workstation. The defined processor names appear in the following file: /usr/sys/include/arch/alpha/hal/cpuconf.h.
You use the cpu global variable to conditionally execute processor-specific code. For example, the following code fragment calls a system-
specific initialization interface for the DEC 3000 Model 500 Alpha Workstation:
.
.
. if (cpu == DEC_3000_500) {
init_3000_500(); }
.
.
.
cpu(9v)
