+ * @Title: GIFieldInfo
+ *
+ * A GIFieldInfo struct represents a field of a struct (see #GIStructInfo),
+ * union (see #GIUnionInfo) or an object (see #GIObjectInfo). The GIFieldInfo
+ * is fetched by calling g_struct_info_get_field(), g_union_info_get_field()
+ * or g_object_info_get_value().
+ * A field has a size, type and a struct offset asssociated and a set of flags,
+ * which is currently #GI_FIELD_IS_READABLE or #GI_FIELD_IS_WRITABLE.
