  19 The \fBpset_bind()\fR function binds the \fBLWP\fR or set of \fBLWPs\fR
  20 specified by \fIidtype\fR and \fIid\fR to the processor set specified by
  21 \fIpset\fR. If \fIopset\fR is not \fINULL\fR, \fBpset_bind()\fR sets the
  22 \fBpsetid_t\fR variable pointed to by \fIopset\fR to the previous processor set
  23 binding of one of the specified \fBLWP\fR, or to \fBPS_NONE\fR if the selected
  24 \fBLWP\fR was not bound.
  25 .sp
  26 .LP
  27 If \fIidtype\fR is \fBP_PID\fR, the binding affects all \fBLWP\fRs of the
  28 process with process \fBID\fR (PID) \fIid\fR.
  29 .sp
  30 .LP
  31 If \fIidtype\fR is \fBP_LWPID\fR, the binding affects the \fBLWP\fR of the
  32 current process with \fBLWP ID\fR \fIid\fR.
  33 .sp
  34 .LP
  35 If \fIidtype\fR is \fBP_TASKID\fR, the binding affects all LWPs of all
  36 processes with task ID \fIid\fR.
  37 .sp
  38 .LP
  39 If \fIidtype\fR is \fBP_PROJID\fR, the binding affects all LWPs of all
  40 processes with project ID \fIid\fR.
  41 .sp
  42 .LP
  43 If \fIidtype\fR is \fBP_ZONEID\fR, the binding affects all LWPs of all
  44 processes with zone ID \fIid\fR.
  45 .sp
  46 .LP
  47 If \fIidtype\fR is \fBP_CTID\fR, the binding affects all LWPs of all processes
  48 with process contract ID \fIid\fR.
  49 .sp
  50 .LP
  51 If \fIid\fR is \fBP_MYID\fR, the specified LWP, process, task, process, zone,
  52 or process contract is the current one.
  53 .sp
  54 .LP
  55 If \fIpset\fR is \fBPS_NONE\fR, the processor set bindings of the specified
  56 LWPs are cleared.
  57 .sp
  58 .LP
  59 If \fIpset\fR is \fBPS_QUERY\fR, the processor set bindings are not changed.
  60 .sp
  61 .LP
  62 If \fIpset\fR is \fBPS_MYID\fR, the specified LWPs are bound to the same
  63 processor set as the caller. If the caller is not bound to a processor set, the
  64 processor set bindings are cleared.
  65 .sp
  66 .LP
  67 The {\fBPRIV_SYS_RES_CONFIG\fR} privilege must be asserted in the effective set
  68 of the calling process or \fIpset\fR must be \fBPS_QUERY\fR.
  69 .sp
  70 .LP
  71 LWPs that have been bound to a processor with \fBprocessor_bind\fR(2) may also
  72 be bound to a processor set if the processor is part of the processor set. If
  73 this occurs, the binding to the processor remains in effect. If the processor
  74 binding is later removed, the processor set binding becomes effective.
  75 .sp
  76 .LP
  77 Processor set bindings are inherited across \fBfork\fR(2) and \fBexec\fR(2).
  79 .LP
  80 Upon successful completion, 0 is returned. Otherwise, \(mi1 is returned and
  81 \fBerrno\fR is set to indicate the error.
