PSET_LIST(2) System Calls PSET_LIST(2)


NAME


pset_list - get list of processor sets

SYNOPSIS


#include <sys/pset.h>

int pset_list(psetid_t *psetlist, uint_t *numpsets);


DESCRIPTION


The pset_list() function returns a list of processor sets in the system.


If numpsets is non-null, then on successful completion the number of
processor sets in the system will be stored in the location pointed to by
numpsets.


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

RETURN VALUES


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

ERRORS


The pset_list() function will fail if:

EFAULT
The location pointed to by psetlist or numpsets was not null
and not writable by the user.


USAGE


If the caller is in a non-global zone and the pools facility is active,
pset_list() returns only the processor set of the pool to which the zone
is bound.
