/**
* G_VARIANT_DICT_INIT:
* @asv: (nullable): a GVariant*
*
* A stack-allocated #GVariantDict must be initialized if it is used
* together with g_auto() to avoid warnings or crashes if function
* returns before g_variant_dict_init() is called on the builder.
* This macro can be used as initializer instead of an explicit
* zeroing a variable when declaring it and a following
* g_variant_dict_init(), but it cannot be assigned to a variable.
*
* The passed @asv has to live long enough for #GVariantDict to gather
* the entries from, as the gathering does not happen in the
* G_VARIANT_DICT_INIT() call, but rather in functions that make sure
* that #GVariantDict is valid. In context where the initialization
* value has to be a constant expression, the only possible value of
* @asv is %NULL. It is still possible to call g_variant_dict_init()
* safely with a different @asv right after the variable was
* initialized with G_VARIANT_DICT_INIT().
*
* |[
* g_autoptr(GVariant) variant = get_asv_variant ();
* g_auto(GVariantDict) dict = G_VARIANT_DICT_INIT (variant);
* ]|

* Since: 2.50
