OpenSolaris 2009.06 - man page for pset_info (opensolaris section 2)

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 pro-
       cessor 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 maxi-
       mum 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  pro-
		 cessor is not a member of the zone's pool's processor set.
