[C con Clase] Warning W8065

[William Morales]

Amigos,

antes que nada, saludarlos y desearles un buen año.

Realmente es mi primer post, pues he sido un ferviente lector de esta lista.

Ahora, estoy tratando de modificar un archivo en C que tengo por ahí (aclaro, no lo he hecho yo), me manda el siguiente warning que quisiera eliminar.

Warning W8065: Call to function 'GetTextExtent' with no prototype in function HB_FUN_DRAWRADIO

Alguien podria decirme que significa?

He tratado de buscar información en "san google", pero no he encontrado algo que realmente me aclare la duda.

Agredeciendole sus finas atenciones de antemano.

William Morales

PD. esta es parte del código
