  14  .Sh DESCRIPTION
  15  The
  16  .Fn memccpy
  17  function
  18  copies bytes from string
  19 -.Fa src
  20 +.Fa s2
  21  to string
  22 -.Fa dst .
  23 +.Fa s1 .
  24  If the character
  25  .Fa c
  26  (as converted to an unsigned char) occurs in the string
  27 -.Fa src ,
  28 +.Fa s2 ,
  29  the copy stops and a pointer to the byte after the copy of
  30  .Fa c
  31  in the string
  32 -.Fa dst
  33 +.Fa s1
  34  is returned.
  35  Otherwise,
  36 -.Fa len
  37 +.Fa n
  38  bytes are copied, and a NULL pointer is returned.
  39 +.Pp
  40 +The source and destination strings should not overlap, as the
  41 +behavior is undefined.
