What peter is saying is that the bzero is necessary because the structure
may change in the future, perhaps adding a new field that termcap does
not know about. Also, other operating systems may implement additional
fields that termcap doesn't know about.
This is why you generally bzero a structure before initializing it, even
if you 'know' you are initializing all the fields. It makes for better
portability and compatibility.
