zone root pathnames and labels
SYNOPSIS

-ltsol [
library...]
#include <tsol/label.h>
char *getzonerootbyid(
zoneid_t zoneid);
char *getzonerootbylabel(
const m_label_t *label);
char *getzonerootbyname(
const char *zonename);
DESCRIPTION
The
getzonerootbyid() function returns the root pathname of
zoneid.
The
getzonerootbylabel() function returns the root pathname of the
zone whose label is
label.
The
getzonerootbyname() function returns the root pathname of
zonename.
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. The returned pathname is relative to the root path of
the caller's zone.
RETURN VALUES
On successful completion, the
getzonerootbyid(),
getzonerootbylabel(), and
getzonerootbyname() functions return a
pointer to a pathname that is allocated within these functions. To
free the storage, use
free(3C). On failure, these functions return
NULL and set
errno to indicate the error.
ERRORS
These functions will fail if:
EFAULT Invalid argument; pointer location is invalid.
EINVAL zoneid invalid, or zone not found or not ready.
ENOENT Zone does not exist.
ENOMEM Unable to allocate pathname.
