Functions: add strSource refers to the string to the end strDestination, covering the end strDestination '\ 0' and add '\ 0',
Description: strSource and the reference memory area can not overlap and strDestination strDestination must have enough space to accommodate strSource string,
Return value: returns a pointer to the strDestination. No return value is reserved to indicate an error.
Note: because wcscat before strDestination additional strSource don't check, this is a potential cause of buffer overflow, therefore, should be paid attention to when using, it is recommended to use wcscat_s instead.
