.Sh DESCRIPTION
These functions implement string manipulation operations over wide character
strings.
For a detailed description, refer to the documents for the respective
single-byte counterpart, such as
.Xr memchr 3 .
The
.Fn wcswcs
function is not a part of
.St -isoC
and
.St -isoC-amd1 ,
the
.Fn wcsstr
function is strongly recommended to be used.

.Sh STANDARDS
These functions conform to
.St -isoC-99
and were first introduced in
.St -isoC-amd1 ,
with the exception of
.Fn wcslcat
and
.Fn wcslcpy ,
which are extensions.
The
.Fn wcswcs
function conforms to
.St -xpg4.2 .
