wcscat - concatenate two wide-character strings
dest, const wchar_t *src);
The wcscat function is the wide-character equivalent
of the strcat function. It copies the wide-character
string pointed to by src, including the terminating
L'0' character, to the end of the wide-character string
pointed to by dest.
The strings may not overlap.
The programmer must ensure that there is room for at least
wcslen(dest)+wcslen(src)+1 wide characters at
wcscat returns dest.
