System Calls                                    processor_info(2)



NAME
     processor_info - determine type and status of a processor

SYNOPSIS
     #include 
     #include 

     int processor_info(processorid_t processorid, processor_info_t *infop);


DESCRIPTION
     The processor_info() function returns the status of the pro-
     cessor  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.
