    NAME

    processor_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 specified 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 specifying 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.
