  19 DESCRIPTION
  20         This function compares not more than <[n]> bytes of the
  21         object pointed to by <[s1]> with the object pointed to by <[s2]>.
  22
  23         This function is identical to <<memcmp>>.

  29         less than zero  according to whether the object pointed to by
  30         <[s1]> is greater than, equal to or less than the object
  31         pointed to by <[s2]>.
