processor_info(2)                                  processor_info(2)


       NAME
             processor_info - get information about a 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_state
                       Either 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 i386, i486, or i860.

             char pi_fputypes[32]
                       A null terminated ASCII string specifying the type
                       of floating point hardware available.  The string
                       consists of zero or more floating point identifier
                       strings, separated by commas.  Each of the floating
                       point identifier strings may be one of i387, or
                       w1167.

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

          Return Values
             On success, processor_info returns 0.  On failure,
             processor_info returns -1 and sets errno to identify the
             error.

          Errors
             In the following conditions, processor_info fails and sets
             errno to:

            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.
