111.Sh DESCRIPTION 44.Sh DESCRIPTION
112These functions implement string manipulation operations over wide-character 45The
113strings. 46.Fn wmemchr
114For a detailed description, refer to documents for the respective single-byte 47function locates the first occurrence of
115counterpart, such as 48.Fa c
116.Xr memchr 3 . 49in wide string
50.Fa b .
51.Sh RETURN VALUES
52The
53.Fn wmemchr
54function returns a pointer to the wide character located, or
55.Dv NULL
56if no such wide character exists within
57.Fa len
58wide characters.
