* @Short_description: Struct representing a struct or union field
|
|
* @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.
