wcsncat - concatenate two wide-character strings
wchar_t *wcsncat(wchar_t *dest, const wchar_t *src, size_t n);
The wcsncat function is the wide-character equivalent of the strncat
function. It copies at most n wide characters from the wide-character
string pointed to by src to the end of the wide-character string
pointed to by dest, and adds a terminating L'\0' character.
The strings may not overlap.
The programmer must ensure that there is room for at least
wcslen(dest)+n+1 wide characters at dest.
wcsncat returns dest.
