getzonelabelbyid(3TSOL) 			       Trusted Extensions Library Functions				   getzonelabelbyid(3TSOL)

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  allo-
       cated 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.
