DESCRIPTION
v12n_env_t is an opaque type. The supported functions, return values,
and errors are described below:
v12n_get_current_env() Returns the current environment. See below
for the list of possible environment names.
v12n_get_parent_env() Returns the parent environment. Currently,
the parent environment can only be detected
from a non-global zone. See below for the
list of possible environment names.
v12n_get_env_prop() Returns a string representation of a re‐
quested property for a given environment.
The returned string must be freed by the
caller.
v12n_list_supported_envs() Fills out a NULL-terminated array with all
supported environments. The array and its
contents must be freed by the caller. NULL
is returned on error.
v12n_list_envs() Fills out a NULL-terminated array with all
known environments in the given class. The
array and its contents must be freed by the
caller. NULL is returned on error.
v12n_list_env_props() Fills out a NULL-terminated array with all
known property types for the given environ‐
ment. The array must be freed by the
caller. NULL is returned on error.
v12n_get_prop_name() Returns a string representation of a vir‐
tual environment property.
v12n_free_env() Frees the storage associated with an
v12n_env_t.
v12n_copy_env() Copies the supplied v12n_env_t. A new
v12n_env_t is returned.
v12n_get_env_type() Returns an integer which represents the
type of the current virtual environment.
The integer is a number of the virt_env_t
enumeration. The virt_env_desc_t array con‐
tains name of virtual environment for each
constant of the virt_env_t enumeration.

LEGACY
int v12n_capabilities();
int v12n_domain_roles();
int v12n_domain_uuid(uuid_t uuid);
size_t v12n_domain_name(char *buf, size_t buflen);
size_t v12n_ctrl_domain(char *buf, size_t buflen);
size_t v12n_chassis_serialno(char *buf, size_t buflen);
The v12n_capabilities() function returns the virtualization capabili‐
ties mask of the current domain. The virtualization capabilities bit
mask consists of the following values:
tab(); lw(2.29i) lw(3.21i) lw(2.29i) lw(3.21i) ValueDescription _
V12N_CAP_SUPPORTEDT{ Virtualization is supported on this domain. T}
V12N_CAP_ENABLEDT{ Virtualization is enabled on this domain. T}
V12N_CAP_IMPL_LDOMST{ Logical Domains is the supported virtualization
implementation. T}
The v12n_domain_roles() function returns the virtualization domain role
mask. The virtualization domain role mask consists of the following
values:
tab(); lw(2.29i) lw(3.21i) lw(2.29i) lw(3.21i) ValueDescription _
V12N_ROLE_CONTROLT{ If the virtualization implementation is Logical Do‐
mains, and this bit is one, the current domain is a control domain. If
this bit is zero, the current domain is a guest domain. T}
V12N_ROLE_IOCurrent domain is an I/O domain. V12N_ROLE_SERVICECurrent
domain is a service domain. V12N_ROLE_ROOTCurrent domain is a root I/O
domain.
The v12n_domain_uuid() function stores the universally unique identi‐
fier (UUID) for the current virtualization domain in the uuid argument.
See the libuuid(3LIB) manual page.
The v12n_domain_name() function stores the name of the current virtual‐
ization domain in the location specified by buf. buflen specifies the
size in bytes of the buffer. If the buffer is too small to hold the
complete null-terminated name, the first buflen bytes of the name are
stored in the buffer. A buffer of size V12N_NAME_MAX is sufficient to
hold any domain name. If buf is NULL or buflen is 0, the name is not
copied into the buffer.
The v12n_ctrl_domain() function stores the control domain or dom0 net‐
work node name of the current domain in the location specified by buf.
Note that a domain's control domain is volatile during a domain migra‐
tion. The information returned by this function might be stale if the
domain was in the process of migrating. buflen specifies the size in
bytes of the buffer. If the buffer is too small to hold the complete
null-terminated name, the first buflen bytes of the name are stored in
the buffer. A buffer of size V12N_NAME_MAX is sufficient to hold the
control domain node name string. If buf is NULL or buflen is 0, the
name is not copied into the buffer.
The v12n_chassis_serialno() function stores the chassis serial number
of the platform on which the current domain is running in the location
specified by buf. Note that the chassis serial number is volatile dur‐
ing a domain migration. The information returned by this function might
be stale if the domain was in the process of migrating. buflen speci‐
fies the size in bytes of the buffer. If the buffer is too small to
hold the complete null-terminated name, the first buflen bytes of the
name are stored in the buffer. A buffer of size V12N_NAME_MAX is suffi‐
cient to hold any chassis serial number string. If buf is NULL or bu‐
flen is 0, the name is not copied into the buffer.
RETURN VALUES
On successful completion, the v12n_get_current_env(), v12n_get_par‐
ent_env() and v12n_copy_env() functions return an opaque pointer to a
v12n_env_t representing an environment. Otherwise, the v12n_get_cur‐
rent_env() function returns NULL and sets errno to indicate the error.
On successful completion, the v12n_get_env_prop() returns a string
holding the property value. the v12n_get_current_env() function returns
NULL and sets errno to indicate the error.
On successful completion, the v12n_list_supported_envs(),
v12n_list_envs(), and v12n_list_env_props() functions return an array.
Otherwise, these functions return NULL and sets errno to indicate the
error.
On successful completion, the v12n_capabilities() and v12n_do‐
main_roles() functions return a non-negative bit mask. Otherwise, the
v12n_domain_roles() function returns -1 and sets errno to indicate the
error.
On successful completion, the v12n_domain_uuid() function returns 0.
Otherwise, the v12n_domain_uuid() function returns -1 and sets errno to
indicate the error.
On successful completion, the v12n_domain_name(), v12n_ctrl_domain(),
and v12n_chassis_serialno() functions return the buffer size required
to hold the full non-terminated string. Otherwise, these functions re‐
turn -1 and set errno to indicate the error.
On successful completion, the v12n_get_env_type() function returns an
integer of the virt_env_t enumeration. See the Enviroments section for
the list of possible values. Otherwise, the function returns
VIRT_ENV_UNKNOWN and sets errno to indicate the error.
