In C, it certainly does.  EOF is returned instead of data
when end-of-file is detected.  An alternative to using an
exception would be to separate the return into two kinds
of information instad of just one; since C doesn't have
tuples, and returning a struct makes for awkward usage,
we could use something like
	io_status new_getc(unsigned char *where);
