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
memchr(3).
The
wcswcs(
)
function is not a part of
ISO/IEC 9899:1990 (``ISO C90'')
and
ISO/IEC 9899/AMD1:1990 (``ISO C90'') ,
the
wcsstr(
)
function is strongly recommended to be used.

STANDARDS
These functions conform to
ISO/IEC 9899:1999 (``ISO C99'')
and were first introduced in
ISO/IEC 9899/AMD1:1990 (``ISO C90'') ,
with the exception of
wcslcat(
)
and
wcslcpy(
),
which are extensions.
The
wcswcs(
)
function conforms to
X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'') .
