Function
Giodbus_gvalue_to_gvariant
since: 2.30
Declaration [src]
GVariant*
g_dbus_gvalue_to_gvariant (
const GValue* gvalue,
const GVariantType* type
)
Description [src]
Converts a GValue
to a GVariant
of the type indicated by the type
parameter.
The conversion is using the following rules:
G_TYPE_STRING
: ‘s’, ‘o’, ‘g’ or ‘ay’G_TYPE_STRV
: ‘as’, ‘ao’ or ‘aay’G_TYPE_BOOLEAN
: ‘b’G_TYPE_UCHAR
: ‘y’G_TYPE_INT
: ‘i’, ‘n’G_TYPE_UINT
: ‘u’, ‘q’G_TYPE_INT64
: ‘x’G_TYPE_UINT64
: ‘t’G_TYPE_DOUBLE
: ‘d’G_TYPE_VARIANT
: AnyGVariantType
This can fail if e.g. gvalue
is of type G_TYPE_STRING
and type
is ‘i’, i.e. G_VARIANT_TYPE_INT32
. It will also fail for any GType
(including e.g. G_TYPE_OBJECT
and G_TYPE_BOXED
derived-types) not
in the table above.
Note that if gvalue
is of type G_TYPE_VARIANT
and its value is
NULL
, the empty GVariant
instance (never NULL
) for type
is
returned (e.g. 0 for scalar types, the empty string for string types,
‘/’ for object path types, the empty array for any array type and so on).
See the g_dbus_gvariant_to_gvalue()
function for how to convert a
GVariant
to a GValue
.

Parameters

Type:
GValue
A

.The data is owned by the caller of the function.
Return value
Type: GVariant
A GVariant
(never floating) of
GVariantType
