processor_info(2)			   System Calls 			processor_info(2)

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  pro-
		 cessor 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.
