pset_info(2)							   System Calls 						      pset_info(2)

NAME
       pset_info - get information about a processor set

SYNOPSIS
       #include <sys/pset.h>

       int pset_info(psetid_t pset, int *type, uint_t *numcpus, processorid_t *cpulist);

DESCRIPTION
       The pset_info() function returns information on the processor set pset.

       If  type  is  non-null,	then on successful completion the type of the processor set will be stored in the location pointed to by type. The
       only type supported for active processor sets is PS_PRIVATE.

       If numcpus is non-null, then on successful completion the number of processors in the processor set will be stored in the location  pointed
       to by numcpus.

       If numcpus and cpulist are both non-null, then cpulist points to a buffer where a list of processors assigned to the processor set is to be
       stored, and numcpus points to the maximum number of processor IDs the buffer can hold. On successful completion, the list of processors	up
       to the maximum buffer size is stored in the buffer pointed to by cpulist.

       If  pset  is  PS_NONE, the list of processors not assigned to any processor set will be stored in the buffer pointed to by cpulist, and the
       number of such processors will be stored in the location pointed to by numcpus.	The location pointed to by type will be set to PS_NONE.

       If pset is PS_MYID, the processor list and number of processors returned will be those of the processor set to which the caller	is  bound.
       If the caller is not bound to a processor set, the result will be equivalent to setting pset to PS_NONE.

RETURN VALUES
       Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS
       The pset_info() function will fail if:

       EFAULT	       The location pointed to by type, numcpus, or cpulist was not null and not writable by the user.

       EINVAL	       An invalid processor set 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.
