NAME

processor_info − get information about one processor

SYNOPSIS

#include <sys/types.h>
#include <sys/processor.h> int processor_info (processorid_t processorid, processor_info_t ∗infop)

DESCRIPTION

processor_info obtains information about a single processor in the system.  The information is returned in the processor_info_t structure pointed to by infop. This structure contains the following fields:

int pi_stateEither P_ONLINE or P_OFFLINE.  If the processor is offline, the other fields are meaningless. 

char pi_processor_type[16]
A null terminated ASCII string specifying the type of processor; one of P_88100, P_88110, P_68040, or P_68030. 

char pi_fputypes[32]A null terminated ASCII string specifying the type of floating point hardware available.  The string consists of the floating point identifier string P_FPU. 

int pi_clockThe frequency of the processor clock, in megahertz, rounded to the nearest integer. 

DIAGNOSTICS

processor_info returns 0 on success, or −1 on failure.  Failure may result from:

EFAULT The infop pointer points to an invalid memory address. 

EINVAL The processorid does not refer to an existing processor. 

EIO The processor to which processorid refers is not operational.
