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 proces-
sor 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 suc-
cessful 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 proces-
sors returned will be those of the processor set to which
the caller is bound. If the caller is not bound to a proces-
sor 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 proces-
