DESCRIPTION
     The functions implement string manipulation operations over wide
     character strings.  For a detailed description, refer to documents for
     the respective single-byte counterpart, such as memchr(3).

STANDARDS
     These functions conform to ISO/IEC 9899:1999 ("ISO C99"), with the
     exception of wcpcpy(), wcpncpy(), wcscasecmp(), wcscasecmp_l(), wcsdup(),
     wcsncasecmp(), wcsncasecmp_l(), and wcsnlen(), which conform to IEEE Std
     1003.1-2008 ("POSIX.1"); and wcslcat() and wcslcpy(), which are
     extensions.
