pset_setattr(2) System Calls pset_setattr(2)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 speci‐
fied by pset. The bitmask of attributes to be set or cleared is speci‐
fied by attr.
The pset_getattr function returns attributes of the processor set spec‐
ified 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(1M) and
pool_set_status(3POOL) for information about enabling
and disabling the pools facility.
