Since the printf() family of functions is writing something to somewhere,
they return the number of bytes written (and -1 if they failed).  If you
want to ignore the return value and be in style (;-)), you can use a void
cast:

	(void)printf(....);

This signals that you are explicitly ignoring the returned value.
