A boolean. If it is true, then the slot contains GBoxed structure whose name is @code{slot-type}.

-Defines the ``simple'' GBoxed structure corresponding to C structure. The slot specification is analogous to CFFI @code{defstruct} slot specification with the addition of @code{inline} option.
+Defines the ``simple'' GBoxed structure corresponding to C structure. The slot specification is analogous to CFFI @code{defstruct} slot specification with the addition of @code{inline} option. This also defines the @var{name}-cstruct CFFI structure definition with equivalent structure.
Example of usage:
@lisp
It is assumed that the variant of structures can be represented as C structures with fields of their ``parent'' structures prepended to them. This assumption breaks when structures include their ``parent'' structure as a first field (this changes the memory alignment and changes offsets of fields).
+This also defines the @var{name}-cstruct, @var{structure-name}-cstruct, @var{structure-name}-cunion CFFI structures definitions with equivalent structures (unions).

For example, for these structures this assumption holds:
@example
union GdkEvent
