 *
 * HINT:
 * The FILE structure usually is a linear buffer, i.e. it has a
 * BASE, a POINTER and a COUNTER. The BASE is a pointer to the
 * start of the buffer, the POINTER tells the actual position in
 * the buffer and the COUNTER tells how many character are still
 * left in the buffer. Hence the CHARS_LEFT macro above, that just
 * returns the COUNTER.
 *   The fpurge() function here clears the buffer, discarding any
 * character that was left. The next read access will first read
 * a new buffer and reset the counter. Thus fpurge() will have to
 * set the COUNTER to 0 and the POINTER to the BASE, indicating that
 * there is no character left to be read and the buffer is empty.
