GI.GObject.Structs.ParamSpecTypeInfo
Description
This structure is used to provide the type system with the information required to initialize and destruct (finalize) a parameter's class and instances thereof. The initialized structure is passed to the g_param_type_register_static() The type system will perform a deep copy of this structure, so its memory does not need to be persistent across invocation of g_param_type_register_static().
- newtype ParamSpecTypeInfo = ParamSpecTypeInfo (ForeignPtr ParamSpecTypeInfo)
- newZeroParamSpecTypeInfo :: MonadIO m => m ParamSpecTypeInfo
- noParamSpecTypeInfo :: Maybe ParamSpecTypeInfo
- paramSpecTypeInfoReadInstanceSize :: ParamSpecTypeInfo -> IO Word16
- paramSpecTypeInfoReadNPreallocs :: ParamSpecTypeInfo -> IO Word16
- paramSpecTypeInfoReadValueType :: ParamSpecTypeInfo -> IO GType
