    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.
