Estructura "Invalida" valida

Notapor PowerDeath » Dom Mar 15, 2015 6:19 am

Buenas, estaba leyendo sobre los Punteros Opacos en Wikipedia y me di cuenta que en C se puede crear una estructura sin miembros, por boludear me dio por escribir el siguiente código.

Código: Seleccionar todo
Importar "Utiles.prp"
Estruc E,:Nulo
Var i:E
Mensaje(EntCad(i@))


Y para mi sorpresa es funcional, intente crear una variable de tipo Nulo, pero parece ser que este no es un tipo de dato valido.
La duda es la siguiente, ¿Que puedo hacer con esta estructura?
Ademas aprobeche a utilizar el procedimiento Long para obtener su tamaño, pero me dio 0 bytes reservados. el chiste es que me da una dirección en memoria, por eso la pregunta anterior.
