GParamSpecTypeInfo: @instance_size: Size of the instance (object) structure. @n_preallocs: Prior to GLib 2.10, it specified the number of pre-allocated (cached) instances to reserve memory for (0 indicates no caching). Since GLib 2.10, it is ignored, since instances are allocated with the [slice allocator][glib-Memory-Slices] now. @instance_init: Location of the instance initialization function (optional). @value_type: The GType of values conforming to this GParamSpec @finalize: The instance finalization function (optional). @value_set_default: Resets a @value to the default value for @pspec (recommended, the default is g_value_reset()), see g_param_value_set_default(). @value_validate: Ensures that the contents of @value comply with the specifications set out by @pspec (optional), see g_param_value_validate(). @values_cmp: Compares @value1 with @value2 according to @pspec (recommended, the default is memcmp()), see g_param_values_cmp().
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().
