pset_bind(2)                     System Calls                     pset_bind(2)

       pset_bind - bind LWPs to a pset

       #include <sys/pset.h>

       int pset_bind(psetid_t pset, idtype_t idtype, id_t id, psetid_t *opset);

       The  pset_bind()  function  binds  the  LWP or set of LWPs specified by
       idtype and id to the pset specified by pset.  If  opset  is  not  NULL,
       pset_bind()  sets the psetid_t variable pointed to by opset to the pre‐
       vious pset binding of one of the specified LWP, or to  PS_NONE  if  the
       selected LWP was not bound.

       If  idtype  is  P_PID, the binding affects all LWPs of the process with
       process ID (PID) id.

       If idtype is P_LWPID, the  binding  affects  the  LWP  of  the  current
       process with LWP ID  id.

       If  idtype  is  P_TASKID, the binding affects all LWPs of all processes
       with task ID id.

       If idtype is P_PROJID, the binding affects all LWPs  of  all  processes
       with project ID id.

       If  idtype  is  P_ZONEID, the binding affects all LWPs of all processes
       with zone ID id.

       If idtype is P_CTID, the binding affects all LWPs of all processes with
       process contract ID id.

       If  id  is  P_MYID, the specified LWP, process, task, project, zone, or
       process contract is the current one.

       If pset is PS_NONE,  the  pset  bindings  of  the  specified  LWPs  are

       If pset is PS_QUERY, the pset bindings are not changed.

       If  pset  is  PS_MYID, the specified LWPs are bound to the same pset as
       the caller. If the caller is not bound to a pset, the pset bindings are

       The  {PRIV_SYS_RES_CONFIG}  privilege must be asserted in the effective
       set of the calling process or pset must be PS_QUERY.

       LWPs that have been bound to a  processor  with  processor_bind(2)  may
       also  be  bound to a pset if the processor is part of the pset. If this
       occurs, the binding to the processor remains in effect. If the  proces‐
       sor binding is later removed, the pset binding becomes effective.

       Pset bindings are inherited across fork(2) and exec(2).

       Upon  successful  completion,  0 is returned. Otherwise, −1 is returned
       and errno is set to indicate the error.

       The pset_bind() function will fail if:

       EBUSY      One of the LWPs is bound to a processor, and  the  specified
                  pset  does  not include that processor, or a process belongs
                  to a different zone than processes currently  bound  to  the

       EFAULT     The  location  pointed  to  by  opset  was  not NULL and not
                  writable by the user.

       EINVAL     An invalid pset  ID was specified; or idtype was not  P_PID,
                  P_LWPID,  P_PROJID,  P_TASKID,  P_ZONEID,  or P_CTID: or the
                  zone of the target threads or processes is bound to a  pool.
                  See pooladm(8).

       ENOTSUP    The  target  pset  is  a  pset created by the resource pools
                  facility. See pooladm(8). Processes can be bound to  regular
                  pools  using  the  poolbind(8) utility or the pool_set_bind‐
                  ing(3POOL) function.

                  Binding a system process to a pset is not supported.

       EPERM      The {PRIV_PROC_OWNER} is not asserted in the  effective  set
                  of the calling process and either the real or effective user
                  ID of the calling process does not match the real or  effec‐
                  tive  user  ID  of  one of the LWPs being bound, or the pset
                  from which one or more of the LWPs are being unbound has the
                  PSET_NOESCAPE attribute set and {PRIV_SYS_RES_CONFIG) is not
                  asserted in the effective set of the  calling  process.  See
                  pset_setattr(2) for more information about pset attributes.
