DESCRIPTION        top

       Thewcsncat() function is the wide-character equivalent of thestrncat(3) function.  It copies at mostn wide characters from the       wide-character string pointed to bysrc to the end of the wide-       character string pointed to bydest, and adds a terminating null       wide character (L'\0').       The strings may not overlap.       The programmer must ensure that there is room for at leastwcslen(dest)+n+1 wide characters atdest.
