9 9 .SH SYNOPSIS
10 10 .LP
11 11 .nf
12 12 #include <sys/pset.h>
13 13
14 14 \fBint\fR \fBpset_bind\fR(\fBpsetid_t\fR \fIpset\fR, \fBidtype_t\fR \fIidtype\fR, \fBid_t\fR \fIid\fR, \fBpsetid_t *\fR\fIopset\fR);

17 17 .SH DESCRIPTION
18 -.sp
19 18 .LP
20 19 The \fBpset_bind()\fR function binds the \fBLWP\fR or set of \fBLWPs\fR
21 20 specified by \fIidtype\fR and \fIid\fR to the processor set specified by
22 21 \fIpset\fR. If \fIopset\fR is not \fINULL\fR, \fBpset_bind()\fR sets the
23 22 \fBpsetid_t\fR variable pointed to by \fIopset\fR to the previous processor set
24 23 binding of one of the specified \fBLWP\fR, or to \fBPS_NONE\fR if the selected
25 24 \fBLWP\fR was not bound.
26 25 .sp
27 26 .LP
28 27 If \fIidtype\fR is \fBP_PID\fR, the binding affects all \fBLWP\fRs of the
29 28 process with process \fBID\fR (PID) \fIid\fR.
30 29 .sp
31 30 .LP
32 31 If \fIidtype\fR is \fBP_LWPID\fR, the binding affects the \fBLWP\fR of the
33 32 current process with \fBLWP ID\fR \fIid\fR.
34 33 .sp
35 34 .LP
36 35 If \fIidtype\fR is \fBP_TASKID\fR, the binding affects all LWPs of all
37 36 processes with task ID \fIid\fR.
38 37 .sp
39 38 .LP
40 39 If \fIidtype\fR is \fBP_PROJID\fR, the binding affects all LWPs of all
41 40 processes with project ID \fIid\fR.
42 41 .sp
43 42 .LP
44 43 If \fIidtype\fR is \fBP_ZONEID\fR, the binding affects all LWPs of all
45 44 processes with zone ID \fIid\fR.
46 45 .sp
47 46 .LP
48 47 If \fIidtype\fR is \fBP_CTID\fR, the binding affects all LWPs of all processes
49 48 with process contract ID \fIid\fR.
50 49 .sp
51 50 .LP
52 51 If \fIid\fR is \fBP_MYID\fR, the specified LWP, process, task, process, zone,
53 52 or process contract is the current one.
54 53 .sp
55 54 .LP
56 55 If \fIpset\fR is \fBPS_NONE\fR, the processor set bindings of the specified
57 56 LWPs are cleared.
58 57 .sp
59 58 .LP
60 59 If \fIpset\fR is \fBPS_QUERY\fR, the processor set bindings are not changed.
61 60 .sp
62 61 .LP
63 62 If \fIpset\fR is \fBPS_MYID\fR, the specified LWPs are bound to the same
64 63 processor set as the caller. If the caller is not bound to a processor set, the
65 64 processor set bindings are cleared.
66 65 .sp
67 66 .LP
68 67 The {\fBPRIV_SYS_RES_CONFIG\fR} privilege must be asserted in the effective set
69 68 of the calling process or \fIpset\fR must be \fBPS_QUERY\fR.

71 70 .LP
72 71 LWPs that have been bound to a processor with \fBprocessor_bind\fR(2) may also
73 72 be bound to a processor set if the processor is part of the processor set. If
74 73 this occurs, the binding to the processor remains in effect. If the processor
75 74 binding is later removed, the processor set binding becomes effective.
76 75 .sp
77 76 .LP
78 77 Processor set bindings are inherited across \fBfork\fR(2) and \fBexec\fR(2).
79 78 .SH RETURN VALUES
80 -.sp
81 79 .LP
82 80 Upon successful completion, 0 is returned. Otherwise, \(mi1 is returned and
83 81 \fBerrno\fR is set to indicate the error.

128 125 utility or the \fBpool_set_binding\fR(3POOL) function.
