 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.
