pset_setattr

, pset_getattr

- set or get processor set attributes

Synopsis

#include <sys/pset.h>intpset_setattr(psetid_tpset,uint_tattr);

intpset_getattr(psetid_tpset,uint_t *attr);

Description

Thepset_setattr() function sets attributes of the processor set specified bypset. The bitmask of attributes to be set or cleared is specifiedbyattr.

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

The value of theattr argument is the bitwise inclusive-OR of theseattributes, 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 bypset_bind(2). When thePSET_NOESCAPE attribute is cleared, a process callingpset_bind() canclear the processor set binding of any LWP whose real or effectiveuser ID matches its own real of effective user ID. SettingPSET_NOESCAPE attribute forcespset_bind() to requires the {PRIV_SYS_RES_CONFIG} privilege to be asserted inthe effective set of the calling process.

Return Values

Upon successful completion, these functions return 0. Otherwise, -1 is returned anderrno is set to indicate the error.

Errors

These function will fail if:

EFAULT

The location pointed to byattr 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. Seepooladm(1M) andpool_set_status(3POOL) for information about enabling and disabling the pools facility.

Attributes

Seeattributes(5) for descriptions of the following attributes:
