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: Any #GVariantType
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).
A #GVariant (never floating) of
#GVariantType type holding the data from gvalue or an empty #GVariant
in case of failure. Free with glib.variant.VariantG.unref.
