.SH DESCRIPTION
.sp
.LP
The \fBlgrp_view()\fR function takes a \fIcookie\fR representing the snapshot
of the lgroup hierarchy obtained from \fBlgrp_init\fR(3LGRP) and returns the
snapshot's view of the lgroup hierarchy.
.sp
.LP
If the given view is \fBLGRP_VIEW_CALLER\fR, the snapshot contains only the
resources that are available to the caller (such as those with respect to
processor sets).  When the view is \fBLGRP_VIEW_OS\fR, the snapshot contains
what is available to the operating system.
.SH RETURN VALUES
.sp
.LP
Upon succesful completion, \fBlgrp_view()\fR returns the view for the snapshot
of the lgroup hierarchy represented by the given cookie.  Otherwise, \(mi1 is
returned and \fBerrno\fR is set to indicate the error.
.SH ERRORS
