True, but the POSIX description for snprintf (s, n, ...) has the 
additional restriction that n must be the size of the buffer referred to 
by s, so POSIX implementations of snprintf can assume that s's size is n 
and that the destination array does not overlap any of the sources, 
regardless of which parts of the destination are written to.
