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 superuser privileges.
The binding of LWPs and processes to processor sets is controlled by pset_bind(2). When 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 require superuser privileges for such an operation.
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.
