DESCRIPTION
     The functions implement string manipulation operations over wide charac-
     ter 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 exten-
     sions.
