PROCESSOR_INFO(2)PROCESSOR_INFO(2)NAMEprocessor_info - determine type and status of a processor
SYNOPSIS
#include <sys/types.h>
#include <sys/processor.h>
int processor_info(processorid_t processorid, processor_info_t *infop);
DESCRIPTION
The processor_info() function returns the status of the processor spec‐
ified by processorid in the processor_info_t structure pointed to by
infop.
The structure processor_info_t contains the following members:
int pi_state;
char pi_processor_type[PI_TYPELEN];
char pi_fputypes[PI_FPUTYPE];
int pi_clock;
The pi_state member is the current state of the processor, either
P_ONLINE, P_OFFLINE, P_NOINTR, P_FAULTED, P_SPARE, or P_POWEROFF.
The pi_processor_type member is a null-terminated ASCII string specify‐
ing the type of the processor.
The pi_fputypes member is a null-terminated ASCII string containing the
comma-separated types of floating-point units (FPUs) attached to the
processor. This string will be empty if no FPU is attached.
The pi_clock member is the processor clock frequency rounded to the
nearest megahertz. It may be 0 if not known.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, −1 is returned
and errno is set to indicate the error.
ERRORS
The processor_info() function will fail if:
EINVAL
An non-existent processor ID was specified.
The caller is in a non-global zone, the pools facility is
active, and the processor is not a member of the zone's
pool's processor set.
EFAULT
The processor_info_t structure pointed to by infop was not
writable by the user.
