GLibVARIANT_BUILDER_INIT_UNSET

A stack-allocated GVariantBuilder must be initialized if it is used together with g_auto(). This macro can be used as initializer when declaring the builder, but it cannot be assigned to a variable.

The builder can be initialized to a specific GVariantType later with g_variant_builder_init().

Use G_VARIANT_BUILDER_INIT() to directly initialize the builder with a specific GVariantType.

  g_auto(GVariantBuilder) builder = G_VARIANT_BUILDER_INIT_UNSET ();

  if (condition)
    return NULL;

  g_variant_builder_init (&builder, G_VARIANT_TYPE ("a{su}"));
  return g_variant_ref_sink (g_variant_builder_end (&builder));
