22 The \fBlgrp_cpus()\fR function takes a \fIcookie\fR representing a snapshot of
23 the lgroup hierarchy obtained from \fBlgrp_init\fR(3LGRP) and returns the
24 number of CPUs in the lgroup specified by \fIlgrp\fR. If both the
25 \fIcpuids\fR[] argument is non-null and the count is non-zero,
26 \fBlgrp_cpus()\fR stores up to the specified count of CPU IDs into the
30 The \fIcontent\fR argument should be set to one of the following values to
31 specify whether the direct contents or everything in this lgroup should be
36 LGRP_CONTENT_ALL /* everything in this lgroup */
37 LGRP_CONTENT_DIRECT /* directly contained in lgroup */
38 LGRP_CONTENT_HIERARCHY /* everything within this hierarchy (for
39 compatibility only, use LGRP_CONTENT_ALL) */
45 The \fBLGRP_CONTENT_HIERARCHY\fR value can still be used, but is being replaced
46 by \fBLGRP_CONTENT_ALL\fR.
50 Upon successful completion, the number of CPUs in the given lgroup is returned.
51 Otherwise, \(mi1 is returned and \fBerrno\fR is set to indicate the error.
55 The \fBlgrp_cpus()\fR function will fail if:
62 The specified cookie, lgroup ID, or one of the flags is not valid.
71 The specified lgroup ID was not found.
