VariantType.first

Determines the first item type of a tuple or dictionary entry type.

This function may only be used with tuple or dictionary entry types, but must not be used with the generic tuple type %G_VARIANT_TYPE_TUPLE.

In the case of a dictionary entry type, this returns the type of the key.

%NULL is returned in case of @type being %G_VARIANT_TYPE_UNIT.

This call, together with g_variant_type_next() provides an iterator interface over tuple and dictionary entry types.

Return: the first item type of @type, or %NULL
