Unix chauvinist!
Not only that, but it's wrong. The function had better have a return
value of int and return EOF or some other value that is guaranteed to
not be a valid character.
And it's not going to work if the attached terminal is line oriented.
Presuming, of course, that the programmer has verified that the
opened file really is a terminal....
The inkey function is almost never as trivial is y'all would like.
When it can be done at all.
