1.44 + * @see_also: #GParamSpecBoxed, g_param_spec_boxed()
1.45 + * @title: Boxed Types
1.46 + *
1.47 + * GBoxed is a generic wrapper mechanism for arbitrary C structures. The only
1.48 + * thing the type system needs to know about the structures is how to copy and
1.49 + * free them, beyond that they are treated as opaque chunks of memory.
1.50 + *
1.51 + * Boxed types are useful for simple value-holder structures like rectangles or
1.52 + * points. They can also be used for wrapping structures defined in non-GObject
1.53 + * based libraries.
