GETZONELABELBYID(3TSOL) Trusted Extensions Library Functions


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.
