 PSET_SETATTR 2 "February 21, 2023"
 NAME
pset_setattr, pset_getattr - set or get processor set attributes
 SYNOPSIS
#include <sys/pset.h>

int pset_setattr(psetid_t pset, uint_t attr);


int pset_getattr(psetid_t pset, uint_t *attr);


 DESCRIPTION
The pset_setattr() function sets attributes of the processor set
specified by pset. The bitmask of attributes to be set or cleared is
specified by attr.

The pset_getattr function returns attributes of the processor set specified by
pset. On successful return, attr will contain the bitmask of
attributes for the specified processor set.

The value of the attr argument is the bitwise inclusive-OR of these
attributes, defined in <sys/pset.h>:
PSET_NOESCAPE

Unbinding of LWPs from the processor set with this attribute requires the
{PRIV_SYS_RES_CONFIG} privilege to be asserted in the effective set of
the calling process.


The binding of LWPs and processes to processor sets is controlled by
pset_bind(2). When the PSET_NOESCAPE attribute is cleared, a
process calling pset_bind() can clear the processor set binding of any
LWP whose real or effective user ID matches its own real of effective user ID.
Setting PSET_NOESCAPE attribute forces pset_bind() to requires the
{PRIV_SYS_RES_CONFIG} privilege to be asserted in the effective set of
the calling process.
 RETURN VALUES
Upon successful completion, these functions return 0. Otherwise, -1 is returned
and errno is set to indicate the error.
 ERRORS
These function will fail if:
EFAULT

The location pointed to by attr was 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.


ENOTSUP

The pools facility is active. See pooladm(8) and
pool_set_status(3POOL) for information about enabling and disabling the
pools facility.
