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(1M) and pool_set_status(3POOL) for information about enabling and  disabling  the
		       pools facility.
