  43 .SH DESCRIPTION
  44 The
  45 .BR wcpcpy ()
  46 function is the wide-character equivalent of the
  47 .BR stpcpy (3)
  48 function.
  49 It copies the wide-character string pointed to by
  50 .IR src ,
  51 including the terminating null wide character (L\(aq\e0\(aq),
  52 to the array pointed to by
  53 .IR dest .
  54 .PP
  55 The strings may not overlap.
  56 .PP
  57 The programmer must ensure that there
  58 is room for at least
  59 .IR wcslen(src)+1
  60 wide characters at
  61 .IR dest .
  62 .SH RETURN VALUE
  63 .BR wcpcpy ()
  64 returns a pointer to the end of the wide-character string
  65 .IR dest ,
  66 that is, a pointer to the terminating null wide character.
