DBusUtilities.gvalueToGvariant

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'][G-VARIANT-TYPE-INT32:CAPS]. 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.
