GETZONELABELBYID 3TSOL "Jul 20, 2007"
NAME
getzonelabelbyid, getzonelabelbyname, getzoneidbylabel - map between zones and labels
SYNOPSIS

cc [flags...] file... -ltsol [library...]

#include <tsol/label.h>

m_label_t *getzonelabelbyid(zoneid_t zoneid);

m_label_t *getzonelabelbyname(const char *zonename);

zoneid_t *getzoneidbylabel(const m_label_t *label);
DESCRIPTION

The getzonelabelbyid() function returns the mandatory access control (MAC) label of zoneid.

The getzonelabelbyname() function returns the MAC label of the zone whose name is zonename.

The getzoneidbylabel() function returns the zone ID of the zone whose label is label.

All of these functions require that the specified zone's state is at least ZONE_IS_READY. The zone of the calling process must dominate the specified zone's label, or the calling process must be in the global zone.

RETURN VALUES

On successful completion, the getzonelabelbyid() and getzonelabelbyname() functions return a pointer to a sensitivity label that is allocated within these functions. To free the storage, use m_label_free(3TSOL). If the zone does not exist, NULL is returned.

On successful completion, the getzoneidbylabel() function returns the zone ID with the matching label. If there is no matching zone, the function returns -1.

ERRORS

The getzonelabelbyid() and getzonelabelbyname() functions will fail if: ENOENT

The specified zone does not exist.

The getzonelabelbyid() function will fail if: ENOENT

No zone corresponds to the specified label.
