Defined in header
wchar_t* wcscat( wchar_t* dest, const wchar_t* src );
Appends a copy of the wide string pointed to by src to the end of the wide string pointed to by dest. The wide character src replaces the null terminator at the end of dest. The resulting wide string is null-terminated.
The behavior is undefined if the destination array is not large enough for the contents of both src and dest and the terminating null wide character.
The behavior is undefined if the strings overlap.
|dest||-||pointer to the null-terminated wide string to append to|
|src||-||pointer to the null-terminated wide string to copy from|
 Return value

Земля, прощай. В добрый путь.
