.SH DESCRIPTION
.sp
.LP
The \fBlgrp_resources()\fR function takes a  cookie  representing  a snapshot of the lgroup hierarchy obtained from \fBlgrp_init\fR(3LGRP) and returns the number of resources in the lgroup specified by \fIlgrp\fR.  The resources are represented by a set of lgroups in which each lgroup directly contains CPU and/or memory resources.
.sp
.LP
The \fItype\fR argument should be set to one of the following values to specify whether the CPU or memory resources should be returned:
.sp
.in +2
.nf
LGRP_RSRC_CPU      /* CPU resources */
LGRP_RSRC_MEM      /* Memory resources */
.fi
.in -2

.sp
.LP
If the \fIlgrpids\fR[] argument is non-null and the \fIcount\fR argument is non-zero, \fBlgrp_resources()\fR stores up to the specified count of lgroup IDs into the \fIlgrpids\fR[] array.
.SH RETURN VALUES
.sp
.LP
Upon  successful  completion,  \fBlgrp_resources()\fR returns the number  of lgroup resources. Otherwise, -1 is returned and \fBerrno\fR is set to indicate the error.
