.TH GETZONELABELBYID 3TSOL "Jul 20, 2007"
.SH NAME
getzonelabelbyid, getzonelabelbyname, getzoneidbylabel \- map between zones and
labels
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [\fIflags\fR...] \fIfile\fR... \fB-ltsol\fR [\fIlibrary\fR...]
.fi
.LP

#include <tsol/label.h>

.fi
.SH DESCRIPTION
.sp
.LP
The \fBgetzonelabelbyid()\fR function returns the mandatory access control
(MAC) label of \fIzoneid\fR.
.sp
.LP
The \fBgetzonelabelbyname()\fR function returns the MAC label of the zone whose
name is \fIzonename\fR.
.sp
.LP
The \fBgetzoneidbylabel()\fR function returns the zone ID of the zone whose
label is \fIlabel\fR.
.sp
.LP
All of these functions require that the specified zone's state is at least
\fBZONE_IS_READY\fR. The zone of the calling process must dominate the
specified zone's label, or the calling process must be in the global zone.
.SH RETURN VALUES
.sp
.LP
On successful completion, the \fBgetzonelabelbyid()\fR and
\fBgetzonelabelbyname()\fR functions return a pointer to a sensitivity label
that is allocated within these functions. To free the storage, use
\fBm_label_free\fR(3TSOL). If the zone does not exist, \fBNULL\fR is returned.
.sp
.LP
On successful completion, the \fBgetzoneidbylabel()\fR function returns the
zone ID with the matching label. If there is no matching zone, the function
returns \fB-1\fR.
.SH ERRORS
.sp
.LP
The \fBgetzonelabelbyid()\fR and \fBgetzonelabelbyname()\fR functions will fail
if:
.sp
.ne 2
.na
\fB\fBENOENT\fR\fR
.ad
.RS 10n
The specified zone does not exist.
.RE
.sp
.LP
The \fBgetzonelabelbyid()\fR function will fail if:
.sp
.ne 2
.na
\fB\fBENOENT\fR\fR
.ad
.RS 10n
No zone corresponds to the specified label.
